All done. Tried dropping the straps, but the one speed nut snapped... so, I pulled the bed. Got the new pump and unit in and now the gauge works and all is well.
I plan to pull the bed again to do my body lift someday and then I'll clean up my frame rails and whatnot. My vent/vapor return line piece on the old unit was cracked in 2 on the old pump when I pulled the bed, so I tried to find another one and no one had one. Then tried to fix mine, not happening. I wound up getting one from my friend's mustang gas tank, and I bought a grommet to make it fit.
