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!!

Has your fuel pressure regulator taken the summer off?

The pressure is adj now!! I set it to 40. And yeah I beleive the pump went bad, thats 2 pumps in like a year!!
And no, my reg worked all the time! I made sure by swaping it to my other mustang and checking!
