Well, I've got a problem with my fuel pressure. I'll set it to around 46-48 psi, and then after a minute or so, it drops down to like 36. I put on a Crane AFPR when I rebuilt the motor, but the cheap bastard I am didn't replace the diaphragm. It looked to be okay, but it had 90K miles on it. Could this be causing it? I have a new fuel pump and filter too. Any help would be greatly appreciated. Thanks.

pull the vacume hose of the fpr if fuel is present in hose replace diaphram you have a leak or else you may have a faulty check valve in your fuel pump

 

Nope, there's no fuel in the vacuum line. I just did the fuel pump a month ago. Any other ideas? Thanks.
