This is what I did with my IHC saddelbag tank: 1: Fill with water and lye, leave out in hot sun a day. 2: Electrolysis; I used a 12v battery, a battery charger to keep it topped up, some jumper cables, and coat hangers as the anode. The tank itself is the cathode. Watch out for hydrogen gas and sparks.

I've had a go with some diluted hydrochloric acid and found that while it works in places there is a lot of crud stuck on the inside (assumedly fuel residue mixed with rust) which doesn't come off unless you scrub it hard or agitate it properly. The tank is baffled in a way that means access to 1/3rd is impossible, and access to 1/3rd is only via a 50mm diameter hole for the fuel sender so i would need to cut it open to properly get at it all. I've found a company who specialise in refurbishing tanks and will cut it open, shot blast the inside and outside and then weld up any holes before coating it inside and out (and giving a warranty on it) It isn't cheap so I am currently deciding if the pain to my wallet from paying them for this is worth the lack of pain from having to do it myself. Based on how my drive, garage and some of my clothes now stink of stale petrol and everytime i touch the tank it is hard to pickup and the underseal on it wipes off and turns my hands black - paying them is currently winning..

Some things are worth buying. My tank adventure took weeks and resulted in a very nasty infection when I cut my hand. Also I ignited some of the hydrogen gas that had collected inside the tank once; That sent hot nasty rust water shooting out the pump hole like a geyser. I had the time to take because the IH had another saddlebag tank that I could run the truck on.

I had mine rigged up from the rafters and I teeter tottered it back and forth with gravel and acid inside. I only coated one of mine, and if I decide I need to mess with the other it's going to a radiator shop.

I shopped mine around to a few old-school radiator shops but they were all like “lol, nope” after I told them I was only able to get 9 gallons out of it from full. So much sludge. Also the length was a problem for a lot of shops that otherwise would have boiled it.

I have now committed to the expensive option and my old tank is getting collected from me on Monday. I also found a cheap used universal 30L plastic fuel tank on ebay which should also arrive on Monday, so I can always stick that in the boot temporarily. It has come out of a kit car so has all the correct connectors that I need and also a level gauge. When I am done with it, then it can go in my other old saab (my project for if we get locked down again) which is currently LPG only without a petrol tank as this is a bit of a dangerous proposition in many places now as there are not as many LPG vendors as there were 10 years ago.

So my ebay tank appeared and is pretty great. I bolted a sheet of wood into the boot and then strapped it in between 2 handy bits of metal. Through a happy coincidence the level gauge hole is the same size as the saab one so I have fitted the saab sender and have a working fuel gauge (which I swear you can watch move down!)   I have since added a 2nd ratchet strap. Then I took it for a test drive and while the worst of the fueling issues were now gone it was still down on power, so i replaced the fuel filter and cut open the old one - it definitely needed doing (brown sludge that came out not pictured)  Also fitted new plugs.. and it made it run properly again! One of my DIY plug leads is a bit dodgy so there is a very occasional miss - and a danger of electric shock if you touch it when the car is running - but overall it has transformed it! So I took it out for a drive and have just done close to 40 miles of test driving with autotune enabled and it now runs really well!  My boost control solenoid isn't working at the moment and I only have about 0.4bar of boost (which i think is the wastegate pressure) but it pulls happily up to that! and is really nice to drive! Got a thumbs up from a guy in a nice TVR who I was able to catch up with on a bendy road, which was nice!  I need to work out what is going on with the boost solenoid - but i'm not too worried yet as low boost is probably a good idea to break it in! I have also had to drop the rear half of my exhaust and do some clearancing work on some of the over axle pipe which was hitting the suspension on bumps. Seems to have worked well!, I have also managed to get the steering wheel straight (by moving it on the splines), which is a little thing but makes a huge difference to how it feels to drive!

Awesome progress! Glad you got the poor running issue sorted. Seems like the list is shrinking so that's always a good feeling. Especially when it's driveable.

I finally got round to installing a radio. This was a £7.50 eBay special which has had the front chopped up to make it fit in the stock 80’s mounting holes and a 3D printed front panel! It did do usb, SD card, fm and Bluetooth, but I had to desolder everything except BT and FM to make it fit. I still need to design and print some knobs or find some old ones that fit. The shafts are not long enough to fit the stock ones:  I have done a high quality mounting job involving an ally offcut and some self tappers and some cable ties.  I also installed a new fuse box cover. I have never had an intact one before  And also, with the help of the AI slack sorted out the breather/PCV setup for the engine (now just a breather!) I have also spent some time hopefully improving the settings for idle speed (it is now running closed loop), and for acceleration enrichment (as it was always briefly going lean under sudden throttle changes)

I have driven 320 miles this weekend and today. Nothing important seems to have broken yet! It sometimes does a little wee out of the header tank overflow when you park up (see photo below, which was taken after a 90 min drive). I think i need to replace the 40 y.o metal cap first. It is also burning/dripping out a little bit of oil. I have had to put about a litre in. Somehow gets 32.4 mpg even when driven at 75/80mph (and i know this is accurate as I can see inside the temporary tank when i fill it up!) Might even be a bit higher than this as I have noticed the odometer has get stuck a couple of times until i pressed the trip reset a few times. I think i need to lube it up a bit inside.   There is sometimes a very horrible noise when I pull off in 1st when on a slope and especially turning left (eg at a junction or a roundabout). I thought it might be the engine mounts flexing and the alternator fins hitting the brake servo but there is no sign of this and it doesn't seem to happen going straight on the flat so i think it may be one end of the left side driveshaft instead. I still cant work out how to get boost control working. My boost solenoid works on the bench when i put 12v into it, and if i measure the connectors in the car I have 12v on one pin and like 0.125 volts on the other when the ignition is on (0v on both with the ignition off) The cheap chinese radio is pretty poo poo. The volume knob is a single speed so it takes about 360 degrees of turning to go between quiet and loud, and it has a lot of engine noise and tends to need powering off and on again after about 45 mins as the BT drops. I might have to work out how to fit a proper stereo.

My daily driver is ill so I have been driving this car quite a lot and just broke 600 miles since getting it back on the road! Over the last few days I have been setting up the boost control and now actually have it making some boost above the 4psi the wastegate is set at! I now have it doing around 10-11psi (0.7/0.75 bar) - which is probably a sensible kind of limit based on the lack of intercooler and how I keep having to use standard (95 RON UK) E10 fuel as premium 98/99RON is hard to find. After running without one for the last few months I bought myself a fancy new oil cooler. Doesn't quite fit perfectly as it is the c900 version and i had to customise the 99 bracketry a tiny bit for it - but it should cool things down a bit!  I was hoping to just get new hoses for the old cooler but the local hose place I found to make them never got back to me to let me know my connectors were in stock and also don't answer their phone and were not in the shop the 2 times i took a trip out there so i had to use the expensive option Unfortunately, it appears that I have an overly abrasive arse and 30 years of sitting in a tent full of mice hasn't done any favours to the upholstery and my drivers seat is starting to come apart   I was expecting it to sag (and bought the seat base repair kit already!) but it appears that the material is separating from its backing and coming apart at the seams  I am going to attempt to swap the drivers and passenger covers and foam around this week so that i can hopefully get that cover fixed or atleast not make it any worse. While I am at it I am going to hand wash all the covers (and hose out the carpet) as the dust levels inside this car are far too high and driving without the windows and sunroof open makes me itch I am having some electrical issues in my dash, the most annoying of which being that my indicator warning light doesnt work. Tonight I pulled it apart and fitted 6 new bulbs and found that all my switches light up once they have working bulbs in! With the installation of some new bulbs in the light fittings I also now have working DRL's/"corner lights" (as they are called in this car)  Unfortunately my indicator warning light still doesn't work properly - though it now comes on with the hazard lights - so i think it is down to the flasher relay not liking the LED indicator bulbs I fitted (cant get filament ones of the correct type and colour so it has to be LED now)

I managed to make the rev counter work!! Looks like the 5v-12v converter circuit that i made was fine but the rev counter in this car was just dead. I tested it in the landrover too (which still has s coil) and it didn't move so I stripped down the dash in my other saab and stole the rev counter out of that... and that one works! Now to find somewhere that can repair the broken rev counter for the other saab.. I have also stripped out the carpet and front seats and attacked the carpet with my pressure washer and lots of carpet shampoo. A lot of brown water came out of these and they now smell pleasantly of carpet shampoo. (I weeded the patio after doing this!)   I also gave the rear seat, headrests and parcel shelf a very light going over with my new toy - a carpet spot cleaner. Cant use much pressure or water as they are very delicate.  I think all my cars are going to get attacked with this thing as watching it suck filthy water out is very satisfying.. Even with a super light going over this much filth came out, and they also now smell of pleasant carpet shampoo  I also scrubbed and pressure washed the floor mats  I have started cleaning all the dash and other interior parts up too. What I can remove has been scrubbed and pressure washed on the patio and the rest is getting scrubbed with antibacterial spray and cleaner in situ.

Hey I got stickied!... I thought the awful app was playing up! All this stuff dried out  And I gave the dash and door trims a good scrubbing and my interior now looks lovely and after being shut up now seems to smell of carpet shampoo and rubber floor mats rather than dust, petrol and mouse nests.  I also attacked the front seats which are bolted together with some bizarre 1970 pre-torx splined recessed head with M6 thread (it appears to be a 12 point T43) bolts that were also corroded into place. I removed them with a combination of a chisel and by hammering a T45 socket in.   unfortunately I discovered that all the foam is hosed so even swapping side-side isnt going to work well I also cant work out to get the headrest section off the back. looks like you might need to unpick it.    I have carpet cleaned all the covers anyway and will ring up some upholstery specialists this week about foam repair. If i cant get anywhere or it seems super expensive I guess I will be buying some blocks of foam and an electric carving knife along with some foam spray glue and perhaps some light fabric to glue onto the surface to hold the dust in. This week I am going to steal the front seats out of my other saab for the moment to keep this one drivable, so fingers crossed it will actually start so i can get the door open enough to scavenge its seats! I have also been trying to diagnose my gear selector being a bit tricky to sometimes find the path between 5th and 3rd/4th. Turns out the centering mechanism is powered by a load of springs and a nylon block which is on the gear selector shaft rather than in the gearbox:  And my gear selector rod:    So I need to sort something out there. The springy bit can still be purchased, so i think I need to buy that, 3D print the block for the middle (and bolt it through the hole), and then modify the metal tray that holds the bottom of the centre console in place and possibly the bottom of the centre console tray!

I stole the seats out of my other car over the weekend while i work out how to fix my proper ones   annoyingly the yellow car has been sat for 1 year now since i last started it and it kicked in immediately on a borrowed battery and with just throttle pedal as the choke cable is broken! Then it was sunny and nice so i went out for a walk in the peak district   It was a lovely day apart from when a wasp came through the window as i was driving and stung me on the arm before dropping off onto my crotch and staggering around. Obviously when i was in a queue of traffic doing 40 on a narrow sunken road with nowhere to pull over.

I went to a car show at the weekend and totally forgot to take any photos other than this one of the awesome green c900 I parked next to! Did some proper shopping on the way home too!  Then today my fuel tank finally returned from being refurbished!  It took them longer than expected because they lost my fuel tank mounting ring while they were shot blasting it and had to remake it from scratch...  ...since they only told me this after finished the job I didn't get the chance to tell them that I actually gave it to them without a mounting ring and I am very happy that they made one for me and welded it on because I was expecting to have to sort that out myself or to have to pay someone else to make me one!  Tank looks really good. Can see where they cut holes into all the sections to clean them all out

I got a range rover fuel pump assembly (which was about £30) and shortened its hanger by about 15mm to make it fit in the 99 tank. I then made up an aluminium adaptor plate and a thick gasket to bolt it onto my new mounting ring.   Then today I refitted it, and replaced the connector on the pump to make it plug into the Saab wiring. I obviously bought the same pump here as Edd China did for his project rangerover on youtube the other week as the wire colours were backward I wanted to get new hangers but the saab parts guy who re-makes them has been out of stock forever so I ended up cleaning up and painting mine and they ended up looking really good! (though i have had to use a couple of nuts to get enough working thread on the pins at the end)  My boat tank has now been decanted into the new tank and the car runs again and the new fuel pump is lovely and quiet compared to the bosch ones!

Failure to complete a clutch replacement on my daily driver Fiat Panda has left me commuting in the Saab this week. 4 days and 340 miles in so far and I am somehow getting: 34 mpg of super unleaded (i'm doing a max of 65-70mph as the wheels are not balanced properly) 2040 mpg of engine oil (predicted based on 750ml used so far) 40 miles per cable tie holding the top radiator hose away from the coil pack where it hits one of the HT leads and causes it to run on 3 cylinders. I need to get a better hose. It almost overheated on day 1 when I hit a bad traffic queue in town but i think this caused it to burp the last of the air out of the cooling system as since then it has been great and hasn't got hot enough to turn the cooling fan on even in worse heavy traffic. The previous unpleasant grinding noise that was coming from around the crank pulley has now totally gone as it has fully ground away the end of the bolt that was in its way (1 of 2 fixings that holds the accelerator pedal return spring, other fixing is hanging in there). The alternator fins now only hit the brake servo when i take speed bumps too fast or hit a big hole. Google maps needs an 'avoid lovely roads' navigation planning option as yesterday it took me on a detour around manchester to avoid some traffic and I stopped counting after the 25th speed bump/massive pothole. New engine mounts arrived today and are now awaiting installation!

I haven't updated this thread in far too long, but I probably should now there is another classic Saab owner on the forums! This has been one of my most successful ever project cars as it has pretty much just worked for the past 18 months. I did blow one of the injector channels on the speeduino ECU which left me stranded one night - but fortunately this happened 10 miles from home and under a mile away from a tow company that my insurance use so it didnt take long to get home. It failed open and resulted in 2 of my injectors flooding the engine till fuel dripped out of the turbo/manifold joint. Which was nice. I also have had one bit of fuel line (the short new rubber section that joins the stock saab nylon line to the T16 engine), split because fuel hose clearly hates E10 but it went on first startup. I have used it to move stuff. This was a 450 mile day drip:  The drivers seat foam was knackered so I bought an electric carving knife and made a new one out of some mattress foam:    New base repair section installed: (old one visible to the rear). The springs on the new ones are as unpleasant to fit as brake shoe springs.   this is the passenger one that just got repaired with some small new sections and then some covers over the top:   This is the repaired drivers seat next to the passenger one (which was still a temporary one out of a later car)  I also have been driving it quite a lot and went past this milestone a few months ago:   and this gets me to here!. I need to sort the paint on the front passenger wing very soon as it is flaking off in big chunks   I now have the car setup almost perfectly at low-pressure turbo boost levels (it maxes out at about 0.5/0.6 bar), so over the next few weeks am probably going to try turning it up a bit! I also replaced the rear engine mounts which stopped the majority of my alternator/brake servo interface issues. I need to find a new front engine mount next as the altator still hits the brake servo sometimes if you give it too many beans when pulling off on a hill...
