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

Lol I'm still needing answers to post 112. But I thought I would give another update since I took the extra 9. In out of the supply line from the sending unit to the pump. I thought it was better until I went for a drive. Just driving normal pressure goes to zero while I'm driving. So it seems by taking the extra hose which made a loop along the frame at the top and back down removed some restriction which made the pump free flowing more. I'm not sure what's going on lol
