My fuel pressure gauge finally came today. I installed it primed the system and started the truck and to my surprise I only had 1 psi on the gauge. I thought ok maybe I there is some air in the system took it for a test drive and no change cept at WOT when it dropped to .5 psi. Of course my 30 day warranty ran out Sat. Oh I forgot I am using an Autometer electic fp gauge. I don't think the gauge is bad I am asuming it is a dead LP. So I am gonna sit down and do some readin to figure out what pump I am gonna replace it with or go stock. If you guys got any ideas feel free to toss them my way. I only hope it didn't hurt the Vp44.

Maybe this would be a good time to put in the Scotty's smart fuel sytem I have been lookin at.

ok I think I am gonna go with the carter 4601hp and the Scotty's. Anyone know where I can get the 3/8 aeroquip fittings for the pump since Scotty's kit is set up for the stock LP
P.S. I tapped my fp gauge into the bottom of the filter.

I KNOW the LP is dead... But The VP44 is on it way... Sorry dude...

I still had 4-5 PSI @ WOT when my LP died. But my VP44 went 2 weeks later...

When I bought my truck I could never really hear the LP running and just figured it was quiet and you couldnt hear it. After about 35,000 miles I started to bomb and when I finally put a FP gauge on it and checked the pressure it was bouncing between 0 and 1 Psi. Obviously, I figured the Lift Pump failed and changed it. After I changed it I could hear it, so now I know that it was dead for at least as long as I had the truck (25,000 Miles) and who knows how long before that (truck had 75 k on it when I bought it). I have since upgraded to a Holley Blue and I now have another 20,000 Miles on the truck since then (120k total), same injection pump, no problems. Points of this story: A: Yes, get a FP gauge or check it regularily with a pocket guage on the schraeder fitting, and B: No, the sky is not necessarily falling. Dont do anything rash with your injection pump. It might be fine for quite a while. Ther are lots of VP failure stories on here mere 'nanoseconds' after the LP failed, but mine was not one of them.

Take it for what its worth, dont loose sleep.

That sux.....install a new LP right away.....I wouldn't even drive the truck until a new LP is on. If you are going with a 4601 all you need are 2 male 3/8" pipe to -8 JIC male hydraulic fitting adaptors to be able to use the Smartfuel on the 4601.

Did I understand correctly that you just bought the truck? You might try to talk to the folks that sold you the truck. It's likely they sold it to you with a bad lift pump and if they do any checking on their vehicles at all they knew it was bad. I'd put a little pressure on and see if they won't at least help with the repair.

I tried talking to the dealer no luck. Anyway I changed the fuel filter today and got 1.5 psi. So I am not driving it gonna beat the Hyundai a bit more till my new LP gets here. I figure if the VP goes it goes I'll deal with that if/when it happens. Thanks for the responses guys.
