fueling problem please help
OK here goes
on idle every thing is fine going up and dawn the RPM on light throttle and all is good
nut once i get on it hard and go above 5000RPM i start to lose pressure
i did some testing to see what is damaged
1-i closed the feed line to the regulator and the fuel pressure went way pass 100PSI , so the fuel pumps are good
2-i burrowed a fuel pressure regulator from a Friend and it showed the exact same symptoms
i guess the only other thing is the fuel filter to change and that is what i will do tomorrow
what do you think guys
