Can I do this without taking off the upper intake? (The instructions say I need to remove it)

Also I bought a in line guage that connects to the shrader valve port. Do I use tepflon tape on the threads?

What do I set the pressure to?

Any advice would be great.

What kind of FPR did you buy??? What intake do you have???

If you're a contorsionist and the screws are in good shape, you can. I've done it before and will never do it again this way. You will have to remove the throttle body and EGR plate to get at it. It's so simple to reomve the upper, your better off and the TB & EGR remains attached.

Use teflon paste out of a tube. This way you don't get any tape into the the fuel lines and clog an injector(s).

39-40 psi with the vacuum disconnected. It's drop to 36 with it connected and a stock cam.

It wasnt easy but I got that focker on their! Its a Cam FPR and I have a GT 40 intake.

I set the pressure at 39 with the vacuum line off. when I connect the vacuum line t goes down to like 25. Does that sound right?

That's stock, you could probably go a little lower.

So the less fuel pressure I allow the more fuel reaches the injectors?
