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

I have another quick question. If I use the same configuration where the pump is located now but add a sump to a new tank or my tank and replumb the hoses. Will that pump work in its current location?
I did that "add-a-sump to a stock tank" thing. Didn't work for me. I put in a bottom feed fuel cell, with the pump below and behind the cell. Problems all solved.
