The Fass I'm looking at requires it's own suction line to be drilled and fitted in the tank, so you may be looking at doing a different setup than I am.
That’s why I asked what year. In later years they went to an intake pump trying to solve the lift pump issues.
As for the draw straw, it’s an easy thing to do. I’ve found that pulling the bed is easier and safer to do than dropping the tank. Get the tank as empty as possible, remove the sending unit, then use an old cool whip container inside the tank to catch any shavings. Drill the hole, then put 4 quarters stacked up flat on each other in the bottom of the tank directly beneath the hole you just drilled. Put the draw straw tube ontop of the quarters, mark the height so you know how much to cut, cut it down, test fit again.
