High Fuel Pressure?
Hey guys i have a 99 Dually with a 5spd and it had a Quadzilla installed already when I got it. I am concerned with the fuel pressure reading on the quad as it normally shows 30+ for fuel pressure readings. Is it likely that it is incorrect or what would cuase the high readings? I have considered putting a true mechanical guage on it but up to this point have not driven it much so have put it off. What are all of your thoughts on this?

What lift pump do you have on it
|
I believe it is the stock one I haven't touched it since I got the truck. I have already read there is no plausible way for this pump to make that kind of pressure. So whats the culprit?
|
I would put money on the quad as i have seen one say the it had pressure of 69psi witch is silly
|
From what he told me when I got the truck he had it installed and it was a quad from a 2001. If that makes any difference IDK. I want to buy a manual guage and hook it up and also upgrade to a raptor lift pump but am waiting until spring for the weather to improve to work on it. I don't do any hot rodding with it with the exception of a couple of pulls during the summer and then pull a goose neck with various loads throughout the summer.

Yea not sure if that would matter but it would be wise to do a gauge
|
definitely do the gauge to get a true reading. May consider swapping out the quad with an edge or smarty. I am pretty sure quad has went out of business. and a fass or etc lift pump is also a must on these trucks if you want the VP to last.
