2001 fuel psi problem
 

just installed a edge juice with attitude monitor on my girlfriends 2001 dodge and its not keeping good fuel pressure at idle its only 9psi and even with the juice set to stock it pulls down to 3psi at anything over 75% throttle and with the juice on 5x5 it pulls down to 0psi at WOT noticed during the install that the truck has a freshly rebuilt vp and i allready checked the banjo bolt and its not leaking

i'm thinkin that the lift pump is shot or at leasting going out....might have been what killed the orginal vp

what's yall's thoughts on this?

I DO NOT trust electric guages at all....I would verify the fuel pressure with a mechanical guage at the test port on the VP-44.

the edge kit replaced the test port.....i'm pretty sure that the readings are correct i was driving it and if you hold the brake to spool it up the pressure drops and so does the power and it doesnt run real smooth

As was said above, I would verify with a MECHANICAL gauge and move down the line from there.

If it is reading correctly I would think the LP would be your next bet, and pray they didn't do an in tank along the way.

While your waitin on a guage to show up you can run a flow test on the LP. Just pull the outgoing hose and run it into a bucket for 1 minute. Multiply by 60 to get gals per hour rate, or the other way around and run a gallon, timing how long it takes. Then multiply it by 60. Comes out the same either way.

If your juicin up her truck make sure you have something better than the stock fuel supply system in it first. These mods will run the VP dry even if the stock LP is working. The stock hoses and LP can't keep up with the fuel needs of the extra HP.

i had the same problem...i could suck my FP down to 4psi at WOT with the hrvp44, stock lift pimp and the edge ez...both the lp and vp44 were new and that was all the lp could supply.. i sence added the holley black and i am at 24 psi all the time no matter where my foot is on the stupid pedal....and i have mechincal gauges...i dont trust electrical gauges either.....

Ive been running a Holly BLUE pump for 2 years no and no problems 20psi, it pulls to 18 at WOT. I kept the LP to keep the psi at its 8psi for start up.

$114 with some hose and HD hoseclamps and I was back on the road!

where can i find more info on the holly blue pumps? any of yall got pics of the install and maybe a link to a place where i can buy one....a new factory pump is like $160 i think is what they quoted me today so if the holly is better for the same money then that's the route we'll go

By far the easiest way is to install Vulcan Big line/relocate kit and get a Holley Blue from Summit or Jegs...

The Holley's have worked great for some and been a complete failure for others. So far the only pump that I have heard no problems with once it's installed is the Walbro. Been a few install problems reported but it has been insatalled in large numbers of the trucks that are over the road and so far 0 failures.
