Fuel pressure questions
was checking my fuel pressure and had a few questions. When the pump primes its at 38-39 and it returns to 31 once the pump is done priming (KOEO). With the engine running I think it was like 32. Does all this sound right? Engine runs great, just doing some checks to see how optimum everything is...

Awesome, thanks guys. One more thing, what fuel pump do you think I have? Based on the info in my sig and the info I've provided
EDIT: I'm also not sure which cam I have (I know - from the previous owner its a Forda Racing - and he thought X303) - I was asking a buddy and he was 99% it was either X or Z303. Wish I could tell for sure with out digging

Well the fuel pump size cant be known unless you look at the pump housing and get the numbers on it.
The cam well man those cams are huge for a stock engine!
Sounds like someone was unsure of what direction to go in IMHO!
You could have a 88-255lph pump and get the same fuel pressure pending regulator function!
