Propane torch took care of the stuck bolt, glad i had that tank off, otherwise that'd be a no go.
Tank holds the full 21 gals, but oddly the fuel pump is quite noisy now. I made sure to fill the tank before running the pump at all, so it would not pump air. Pressure seems ok, car runs and accelerates as normal, but what would make the pump go noisy all of a sudden? I made sure the pump was clipped into the piece at the bottom of the tank,so i don't think that is the problem.
