Engine/Transmission (1998.5 - 2002) Normal Vulcan kit and new lift pump pressures?

[BDrawdy]

I've installed a Vulcan big line kit and a new lift pump. I'm seeing 13psi cruise, and 10 WOT with no load. I've seen higher on this board. Are my pressures normal? Should I be concerned?



Thanks for all the great information guys...

I don't see why that is bad. Anything over 5psi is supposed to be fine.

you are getting the same as I am. it is just fine.

I just recently installed the Vulcan relocation and big line kit and I'm seeing 14 psi at idle and I can only drag it down to 10 psi at WOT when fully loaded. That's with the original LP (65k miles).



Before the pump was relocated, I could drag it down to 0 at WOT.

Really IMO as long as you are showing pressure, that means the lift pump is suppling enough fuel to the injection pump.
