It seems like I get a different answer to this question every time I ask it, so this may be an exercise in futility, but here goes. I have an 01 24valve with an Edge EZ module that adds 65hp, bringing total hp to 300. What is the safe minimum fuel pressure to my VP44 as measured at the banjo bolt? Bluechip diesel says 5psi, I have been told everything from 2psi to 10 psi.
HELP!

 

There are a lot of opinions on this one.

I would like to see no less than 7psi mysel. This is because of the pressure drop on the VP side of the banjo. This is only my opinion.

I think one of the manufacturers said that 5psi was required to completely fill the fuel needs. I would err on the side of caution. If you can get 12psi at all conditions, why wouldn't you?
