not so!----------I run a fast 2.0 w/ the sock removed and the orig. type 3/8" pick up as a return, I watch my fuel pressure live on the hand held screen mounted on my dash, and it doesn`t waiver over 1-2 pounds. External pump mounted behind the tank, w/ dual 3/8" pipe pick ups in back of tank, going to duel 1/2" filters before pump. No problems! No corvette crap needed!
