ok guys Ive been having horrible problems w the fuel pressure being extremly high!! I was told that my return line was clogged and different things and ideas, I have another mustang parts car and I decided to swap the tanks, it had a factory fuel pump and the one w the high fuel pressure had a bbk 255lph pump. when I swaped it, everything worked again the fuel pressure was at 40 and it ran pretty good!! I was so surprised!!
