Engine/Transmission (1998.5 - 2002) Orignal -v- Intank lift pump

[Michael Hughes]

Just want to see if we can get some numbers on number of VP44s that have/have not failed on each type of pump.

Okay, it should be lift and not left. I don't know if you can edit a poll.

I'm at just over 95,000 miles and still going, but I'm thinking about going to a FASS 150/95. I talked to Tony at Midwest Injection about it, and he schooled me good... nice guy.

The first VP and lift pump was replaced at 88240, (Dodge Dealer) and tomorrow I'm having the VP replaced again at 151000, because it leaks, and I can't figure from where.

Already put on a FASS 95 pump last week.

Even with a leaking Inj. pump it runs stronger / better.

fass II pump they work ok

The year of the truck may have more to do with VP44 failures than a lot of other things, along with hot weather. I have the original lift pump now on the frame and it puts out 15+ lbs at idle, 13-14 at cruise and 11-12 at WOT. When it was on the engine it put out 6-8 at WOT.



Last fall in the hot SW weather, I had hard starting. I month or so ago I had dead pedal a couple of times and got a 216 error. MWFI was great to deal with for a new VP44. BTW only 52K on the truck. "Can you say brass bore on the pump!"



Flynes, tell us what Tony had to say!

Well, he schooled me on the differences between the 95 series and the 150 series. The thing I like about the 150 series is that you can get replacement filters from Fleetguard... . I guess you can't with the 95 series? I asked him about placement of the pump, and he suggested that the optimal placement is closest to the tank, which makes sense. I was surprised to hear that the setup weighs 30lbs.



He also suggested bypassing the OE pump completely, but leaving the OE water separator in place, theory being that overkill in that department is good. I like Midwest Fuel Injection's price on the setup of the 150/95 ($635. 55). As far as which model is best for my application (I am bone stock with no intention of modding the motor), the 95GPH is more than adequate for what I need.



I asked him about what kind of pressure I could expect with the FASS, and he told me that 16psi is normal, with a drop of no more than 1psi at WOT and towing. He also said that the Dodge retrofit of the in-tank pumps is a disaster waiting to happen; doesn't provide near enough pressure to the VP44, and it's a MOPAR part, not Cummins, so you can only get the part through Dodge.



Installation takes one hour, according to him. All I have to do is give him a heads up and he can order what I need. I'm on my way to Arizona in May for school, and I'm taking two weeks of leave, so I think I'm going to swing out his way and get this done.

In-tank Lift pump

I've got a late model '02. At around 50K, DC replaced the VP44(as well as a major rebuild of the 47RE). At about 75K, I was getting nervous about my fuel pressure(anywhere from 14 to 5, all over the place). I took it in and DC retrofitted the intank pump. For about a year, I have had about 6-8psi at idle, and 1-3 at WOT(or almost WOT).

The truck was bone-stock when the first VP went; it was essentially stock(AFE)

when the lp was replaced with an Intank.

stock lift pump same location with Olee's big line kit and fp guage



400 hp and no fuel pressure issues and that 6 years and 70K miles :-laf



only went through 2 lift pumps too
