Hooray!
I got it loose! As Slaid Cleaves said in
"Drinkin' Days", sometimes you gotta act like you've got a pair. So, I made a bid for the
Darwin Awards.
I cut into the fuel filter's nut, slotting it with my dremel's diamond cutoff wheel most of the way to the thread. Some sparks flew but not a lot. I had wiped up the area so there were no pools/drops of fuel around. I couldn't get all the way across the width of the nut but two corner cuts did the job. It wasn't enough to crack the nut but it relieved enough stress on the nut for me to brute-force the nuts until they were persuaded to cooperate.
For how badly it was stuck, the threads sure look clean and uncorroded. WTF?
The saga continues. I ran the fuel pump and I don't think I got a whole gallon out. I'm pretty sure there should be at least 3 gallons of the worst stuff still in there.
