I have a AEM fuel rail and a ssx fuel pressure regulator. I just installed a fuel pressure gauge and I was wondering if someone would know a good psi to put it at?

thanks for the info . I had it set at 58 psi. when you talk about the vacum line are you talking about the gold little prong that sticks out at the top where you adjust the pressure. Also what will cause my car to idle up and down when setting still

That's correct, Do not hook up the vacuum.

The K-series ECU doesn't want to see fuel pressure that fluctuates with vacuum.

brian g
is that the same even with the type-r ecu?
Yes

Air in the cooling system, or a vacuum leak, or a cable that too tight.

I just got mine running the other day. I'm using the aem universal fpr. Above 40 psi it starts pulsating like mad. It doesnt at 40. I took it for a quick spin at 40psi and it ran fine, but when I get it up and going I want it set correctly. Any help from brian g since I'm running your mounts, axles, headers, and wiring! lol
