I've had this Holley adjustable fuel pressure regulator sitting in the back of my car for the past 2 yrs. I pulled plenum off today and put it in. When I started the car with the pressure guage hooked up to fuel rail, the most I could get out of it was about 45 psi. Am I missing something simple or is my fuel pump on the way out? I noticed that when I gun the engine, the fuel pressure jumps to about 50 psi. Anyway, I can't search for anything ('cept w/ google). Someone tell me what I'm seeing is normal.

 

well aaron are you disconnecting the vacum line when your checking the fuel pressure?

make sure that the vaccum line is disconnected when checking fuel pressure,

 

disconnected and pluged mind you.

also check how fast the pressure bleeds down after you kill the engine.

 

Sweet. I picked up a guage that has a clear plastic hose on it. Dunno if I'm supposed to connect that to the vacuum on the afpr. I hadn't disconnected the vacuum line though. I'll give it another try.

Thanks guys.

Btw... are we still on for dyno day on Sunday? What time should I show up?

 

Yes we're still on for Sunday, time is TBA, but I'm sure anytime after 9-10am should be fine.
Check back again by Friday in the GTG thread and we'll have the latest.
Should be a great 70* weekend.

 

I hope so because its been crap lately.

 

yeah, no doubt.
extended forecasts say all clear by friday.
should be high 60's-70 sat/sun.

 

I can't wait im all giddy like a school girl.
