Fuel pressure dropping while driving and under acceleration to zero at idle runs 4 lb electric Blue

you wouldn't happen to have a picture of that would you. I'm not sure what that looks like or I may have seen it not know what it's called lol
99% of fuel cells are bottom feed, just look at listing of fuel cells at jegs or summit.
Mine is in the trunk, with one feed line plugged (they usually seem to have two -8s, I change to one -10, out to a pump to the rear of the cell, (140gph trickflow in one car, 250gph Mallory gerotor in the other) then a fuel filter, then an aluminum 1/2 line to the dead head regulator. Stupid basic, but it works for me.
