i just did an engine swap in my '88 and after figuring out that i had my fuel lines reversed, i re-attached everything and had about 60psi fuel pressure at my FPR. after i cranked my engine a bit i noticed my pressure drop untill it was about 15ish psi and would not re-gain pressure. after tracing the problem i discovered my pulsation dampener was letting absolutely no fuel into my rail.
What im wondering is did i wreck it from too much fuel pressure? maybe the fuel being reversed popped something out of place? has anyone run into this problem before or is it just a freak scenario?

 

So u have an aftermarket fuel pressure regulator? If so then remove the damper. Most FPR come with built in damper no need to run the leaky stock one..

 

Yea i do have a after market FPR. Ill just take it out and not catch my car on fire. Thanks!
