Engine/Transmission (1998.5 - 2002) High milage original VP44

[Ray Torresdal]

I'm curious as to how many miles anyone has gotten on a VP44 pump. I have 148,000 on mine - anyone with 200, or more???



TIA

Don't look for alot of replys on this one. I got 135,000 before mine took a dump, still have original lift pump @145,000 go figure.

I've got 134000 an my 99 and just got done replacing the lift pump, but no problems yet with the VP44.

jinx factor

If I reply, will mine die ?? :{ 178K+. One lift pump replaced.

 

[mcoleman]

I've got 131,600 on mine and still ticking with one lift pump replacement. One of the highest I know of is 78repowerwagon. I believe he has around 225,000 on his and runs low 13 second 1/4s to boot with it. But I think he has always carefully watched his lift pump pressures.

HVAC's Red Rocket still has the original VP in it... . last dyno about a week before his death he was at about 780 HP +/- a couple

You beat me to it Gary! I believe he's runnin' the ol' '53' block as well. If that isn't a 1,000,000-mile engine, I don't know whose is.

If I tell you how many miles I got on mine it will probable go out, I have pulled travel trailers heavy construction trailers with it and no trouble so far,I have 220,000 miles on it.

257,000 I just keep feeding it power service. Thinking of getting a comp just to see what happens. It has had the mod's below since day one, and towed 8-10K most of it's life.

Hey Ray! If you got some $$$ laying around, I can fix that problem for ya. I guarantee I can kill your pump before 200,000 if you give me the chance. Oo.

Where exactly is the VP44 ? and is it mechanical ?

and is the lift pump before or after the VP44.

 

[JCockrell]

VP44 is on the driver side of the engine compartment, close to the radiator. The are six injector lines running from it to the head, right there on top can't miss it. Could be classified as electro-mechanical , it is computer driven. The lift pump is before the VP44 in the fuel flow. It is on the same side of the engine compartment under the fuel filter.



This may help. Click on photo overview in the 3rd post.

The (Bosch) VP-44 is your injection pump... It's a mechanical pump that is controlled with electric solenoids. It even has a brain inside it that communicates with the outside world using CAN-BUS.



In the fuel flow scenario, the lift pump would come before the VP-44 injection pump... .

On edit: Wow! That must be some kind of record... . we both posted at the same time! :-laf

brother in law has 175k on his, 150k tapped with an edge comp. 1 LP replacement.

I have a few of these trucks. The one with the most miles has 210k miles on it. I put a drag comp on it the day I bought it. I dynoed 1482 lb/ft of torque Monday night with this truck. I put a holley black pump on all of my trucks and trash the stock lift pump. I think the holley pump is what has kept all my vp 44s alive. They will probably all die tomorrow since I'm bragging on them.

I didn't realize that Dodge had ever used a

rotary pump (vp-44), all I had ever seen was what

I call the plunger type where the lines are fixed

in a straight line from the top of the injector

pump, like the truck I wanted to buy back in

'95 or '96. This VP-44 appears similar to the

Roosa Master rotary pump used on small to medium size

tractors and used on the Olds 5. 7L like I had

which was rebuilt by GM every 30 to 33 thousand

miles. The last time they put a stainless steel

kit in it and it never gave anymore trouble. Any

thing like varnish or nylon breaks loose in the

pump it clogs the check valve where the return

line fits onto the pump and you're afoot unless

you have something to take it off and clean

the little ball and spring in the valve.

Actually the 89 through 93's all had the Bosch VE rotary pump in them. fyi
