just some questions

i've seen on here a few things about a cali model for our engines. what is that and how do you know if yours is one.

is there any real gain in shimming your FPR, and what should the fuel pressure be setting around so if i do i dont blow anything.

and i have recently discovered fuel inside the valley i cant tell where its leaking from yet, i'm going to get int there and clean out the valley so i can see where its leaking from, but suggestions as to where and how to fix it would be greatly appreciated.

thanks

there is a sticker on the pass side valve cover that will tell you if it is a cali model. also, the fuel pump looks like a flying saucer. see the disc under the turbo?...

If you don't have a cali model stock fuel pressure is between 45-55psi. Optimal is about 65-75psi, but you do NOT want it over 80psi at idle.

70psi is about perfect.

Like you said, could be. Could also be the filter housing or a fuel line. Probably gonna do just what you said and clean it out to find out for sure where its coming from.

cali engines also have larrger, 120cc split shot injectors vs the stock 49 state 90cc single shot injectors. makes a little difference in the git up

you could have one of the old fuel lines cracked from heat and weaping, of the fuel pump could leak out the weaphole under the bajo bolt. best way is to clean up and watch were it pools from.

i myself have come to the conclusion on a diesel, if its not leaking, something is wrong LOL
