^^ I... What? I need more angles! Gonna crosspost this from my thread because it's definitely a horrible mechanical failure. gently caress you, AEM fuel pump. A mate came over today and we decided we were going to install the new fuel pump, plumb in the flex-fuel sensor, and maybe install the wideband. As you can guess, this did not happen.  This was a brand new out of the box AEM 50-1215 fuel pump, I dropped it into my Legacy (it is a drop-in, 320lph @ 43.5psi, ethanol and methanol compatible pump) and it just went -clik-. No whir. No fuel pressure. Womp womp. So having had to remove/reinstall the pump/filter (in-tank filter...) assembly like five times (because I had to reinstall the old pump to make the thing move), six hours after starting what should have been a simple job, I decided to disassemble it out of rage. Enter Dremel. I discovered why it was DOA. I had dropped it earlier (while still wrapped in bubblewrap) and damaged an inconsequential part of the connector; I was convinced that me dropping it was what killed it, but nope!  See that little sort of raised plastic nubbin left behind by the casting mold? That used to be ~3.5mm high, before I trimmed it. I should have taken a photo before I trimmed it, but I was angry, and I wanted to know if I was right. I was. The little raised plastic nubbin (of which there were two, only one high enough to be a problem) was running into this plastic channel cast into the upper case section;  It's not really visible in the photo but if you look inside with a flashlight you can actually see marks on the plastic where said nubbin/sprue was running into the plastic. This basically meant that instead of spinning at however many RPM, the pump had just slightly under one rotation of function. How the poo poo this passed QC is beyond me. Had I known this was the problem I likely could have just run the pump back and forth a few times to machine the plastic down, but of course that would have just clogged up the pump outlet. I might have to send a disgruntled email to AEM. instead i have just ordered two more pumps with the fastest shipping i could find as apparently nobody in australia stocks them On the plus side, I did discover that the impeller for the pump (which is like 4mm thick) is 3D printed (out of metal); it has the visible layers you expect from 3D printing and also some fairly impossible-to-cast-or-machine structures. Pretty neat.

I knew someone who was an engineer at AFCO (joint Bosch/Denso operation but mostly Bosch engineering culture) and when they did tear-downs of competitors' pumps they were consistently appalled at the quality they saw. They also would get back a depressing number of pumps that had "failed" and been replaced by dealers that were 100% fine. Can't charge $800 for "re-seated connector, works fine now". I remember him talking about how when E10 and E85 first became a thing they were having a hell of a time getting an ethanol-compatible brush-commutator system to hit the automaker's lifetime requirements, not to mention their own internal lifetime requirements. So they got their hands on a box of the pumps a competitor was pitching to the automaker as meeting their requirements and found out that they were just straight up lying about lifetime because they were just using the same system that they used non-blended gas which ethanol would wreck in a relatively short amount of time.

How do you even test a fuel pump for lifetime? Most of its lifetime is spent sitting in stale gas while the car is not being driven for 19 out of its 20 years of existence. Any more fuel pump factory stories? Competitor tear down stories are the best.

Estimations. You keep many of them running for an amount of time and, with a bit of the good old heuristic sense and material spec sheet, extrapolate based on damage/wear. Or just lie out your rear end.

Yup. Put it in a bath of water-saturated E10 and heat it up to simulate years of aging in a few weeks, then start/stop cycle the hell out of it with restricted flow in to simulate heavy use with a partially clogged intake strainer. Running it at higher temperature and high voltage for long periods of time lets you get a good estimate of wear rates for the electrical components as well. My favorite story though was about how they were providing a new model of fuel pump assembly for a redesigned sedan from one of the big 3. Everything was great until the initial vehicles off the line showed a tendency to damage part of the fuel pump assembly during heavy maneuvering with a half tank of fuel. They (fuel pump Co + automaker) tracked it down to the fuel tank manufacturer having omitted a rather important baffle but also during the testing the automaker engineers figured out that a strategically placed fuel resistant zip tie was enough to prevent the damage for occurring anyway. The German company contacts were all in favor of saying that the part met spec and it wasn't their problem but the American engineers and management pointed out that the automaker would need to stop production (and accepting fuel pump shipments) to get new fuel tanks. The end result was they let the the automaker choose what color zip tie they would like. This was a while ago but he could pull out an absolutely amazing rant about the "E10 compatible cars will be just fine with E15" bullshit being advanced in support of E15.

The front end is oddly un-deformed, but you can see where the impact was under the left headlight. Maybe the pole was secured to the ground with balsa wood or something.

My guess is that something else hit the pole, it swung up and the Mercury wound up under it's inevitable return trip to Earth.

Most light poles are designed to break off at the bottom so they don't murder the guy crashing into them like trees do.

So I bought a "Ran when parked 5 years ago", not registered in 20 years, no paperwork Suzuki TS250 for $325, because what can go wrong with that, right? Got it running same day, and noticed half the electrical system didn't work, and it was woefully hard to kick over (Also the kickstarter would jam after every 3 or 4 tries), took a drat good kick to start, and wouldn't idle under ~2000RPM (This being after we fixed its carb and replaced everything made of rubber). So, after it running beautifully on country back roads for ~20 miles at 60MPH, it wouldn't start the next the day. No spark, no power, nothing. We traced the wiring back to the magneto, and pulled off the cover to look.  "Hey, why are all these wires falling out, is something broken under.. Oh.."  I have no idea how the bike even ran at those speeds. One coil was completely free inside the case spinning like a washing machine with the missing metal still connected to it, and the others were held together with hope. It didn't even make any scary noises. How on earth does that break like that? PhoenixWing fucked around with this message at 04:25 on Feb 22, 2016 |

You'll probably find some bent to poo poo screws somewhere as well. When you have the stator off, replace the crank seal too; it looks to be as old as the bike, and is probably leaking.

I am guessing that there is a missing section of pole about 1.5m in height (based on the triangular sign being 2m off the ground before crash). Car hits pole, bottom section flies off forwards out of shot, car stops, rest of pole lands vertically on car bonnet - suspended by cables above,

I know the east side of Russia gets a lot of Japanese imports, so much that the sheer amount of RHD cars there (in a LHD country) is a problem. Don't see why they wouldn't import from America too, what with the US being RHD.

I get that it obviously got imported my dads buddy used to import cars to Russia (via finland so they didnt get stolen) But it was only big American SUV's cop cars, and limos. And the orders came first. The fact that someone in Russia would want that pile of poo poo and pay out the rear end to import it is what im having trouble with. This guy is on my level Godholio posted:I'm more curious about why. Especially since it's a derivative of the Mondeo anyway. thinking about it I would wager it was brought over by an American troop stationed in Germany or something, promptly stolen and resold in Russia.

Ive seen an imported LHD Saab 9-2x in the UK. It's not like we don't have Subaru's here. You could probably import all the special snowflake SAAB bits from the UK for the same hassle as importing then driving an obscure badge engineered car with the steering wheel on the wrong side. Although I guess US forces stationed in the UK may explain some weird imports to the UK, which wouldn't be a thing in Russia, but it might have been an ex pat returning home. The moment I saw that 9-2x my first thought was that I wanted it
