Engine/Transmission (1998.5 - 2002) fuel pressure at idle and WOT on an 01

[PKozlowski]

I just had a Juice with Attitude installed.

While I am not happy with the added performance

I also notice that at idle I have 10 psi

and at 3/4 or WOT I have had 0 to 3 psi.



I just had the lift pump replace again and this one

is in the tank. That was about 3 months ago.



So I'm wondering is this fuel pressure

to low?



Oh forgot to add that on ICE, STOCK(no box) I couldn't get

the truck to break loose or even spin the tires in 4x4

but Dodge says that is normal and the truck is fine.

I bet to differ since I just tapped the brakes and slid past your

driveway!!! Needless to say they're either lazy or couldn't

care less. I'm thinking both.

After relocating my LP and eliminating ALL banjo fittings, the new LP new LP provides 15psi pre-filter. This with the Smarty on level 7 and the accelerator on thje floor with boost at 28 psi.

I think the banjos are way more restrictive than most of us think.

Did you check your fuel filter??



I installed a HPFP on my brothers 99 and my 99 and we are having good luck with them untill today he had very low fuel pressure so we checked his filter and sure enough it was BLACK, Replaced it and on the road again



Also I ordered for the 2 trucks a 1/2" suction tube from DPP that goes in the tank, It should help a bit considering the factory suction tube is only 5/16":-laf

Here is the part #

does anyone have pics of DPP's 1/2in. draw tube? I'm just wondering how it compares to Vulcan's Draw Straw in construction and installation.

There was a thread about someone built (homemade) a large draw tube and had problems keeping a suction on it (ie suction was collapsing because the cross section area was too big).



I did the draw straw and pleased with it, but not a lot of mods or high hp. It has like 3/8" id and matches the rest of my AN-6 plumbing.

Definitely a fuel pressure issue there. 10-14psi at idle, no less than 6psi at any time.

Thanks. I am trying to get it into the shop this week.

A friend of mine just put a edge juice on his 01, his fuel pressure was also reading around 2psi. And his boost would not get over 26psi. I find the boost reading a little weird because my truck will hit 30 to 32 psi with no box just jammer 1's and a boost elbow that came with an ez! Sounds like my guage or his is wrong?? He has the boost elbow in and the wire tapped!!
