Initially I throw this up: another power switch that will shut off the refinery if crude reaches a minimal level, arbitrarily set at 500 here. Note that I can't connect the network to the refinery itself directly. This will work, but isn't optimal. When supply gets down to that level, it will be constantly shutting off and on. What would be better is to have it shut off at 500, then restart at say 5k. Then it would run for a while, turn off when supply is too low, then turn on when it's got enough to do another burst of activity.

Actually making that happen is a bit more complicated. After spending far too much time and not being able to make it work, I decided to move on. I know it can be done, but my brain isn't connecting the dots on how to accomplish it. So I'll stick at simply an on/off at 500 crude here. Added another storage tank of each type while I was at it; petroleum gas is more than half full at 14k+, the others close to half at over 11k. Don't want to run out of space.
