It would seem there are probaly 1,000,000 VP44's on the road ( Dodge alone, assuming 250k trucks sold per year), for 1998 to 2002, more or less. From everything I have read, it is not if the VP44 will fail, but when. In a long thread about "Your VP44 Faialure", it seems apparent many fail betwen 50 & 75k miles and fail after that at similar intervals. It seems a high percentage die in hot weather.
That being said, you would think somebody could make an improved VP44 that can routinely go 150k miles, not 50.When you look at the numbers, 1,000,000 5.9 owners facig VP failure(even with adequate LP pressure & gauge), spending $1000, or $1 Billion dollars per cycle of this fleet. The numbers may be a little off, but probaly not by a lot.
I know some CTD's go much further, but 50-100k proably covers 80-90%
of the fleet, from what I read.
Is there a pump made that will be guarenteed to last 150k? It is sad/pathetic that we have this lemon on our CTD's . Cummins/Chrysler should warrant this for at least 150k, regardless of time.
So, what is THE BEST VP44 replacement and how long can it be expected to last?
These trucks are GREAT, other than this seriuosly deective, poorly designed IP pump.
Soultions?
I still do not know why there is not a class action on this.
How well do the G3 on up work compared to VP44?

 

gm 6.5 diesel had more pump problems.

 

p pump it and forget the vp

 

mine went to 181000

 

the pump itself doesnt fail its the electronics most of the time.

 

Best life improvement is making sure adequate fuel is constantlly supplied to IP. Lift pump failures are big cause of VP44 failures. Mine went 208,000 and failed with LP.

 

I got 85k out of my first vp44.

I think one of the Admins here has over 200K on his original VP44, I wanna say it is Shovelhead.

 

I put over 200k Miles on my vp44 before I changed it, it didn't die, just didn't want to push my luck and had a long trip towing coming up. I siwtched my thermostat to a 180, and try to keep the fuel tank over 1/2 at all times.

 

I think the VP-44 is a pretty amazing IP given that mine was still working despite having no pressure at all from the P O S stock transfer pump when I discovered this site and got it checked. I got a noticeable hesitation when starting for the first while after installing the FASS pump but thanks to Sea Foam (the magic snake oil!) that has cleared up.

I'm sure the Roosamaster rotary pump still holds the record. Funny thing is, those who are familar with it think it is a great pump!!!
Those of us who had a p-7100 pump KNOW the vp is a lot lower in design quality.
Not every shop that rebuild the vp can do a quality job on it. A very experienced diesel mechanic that I've know a long time told me that when I need to replace it find the guy who cares about it and isn't just about numbers and bragging rights.
That is why I bought from Chip.

 

After one bad experience with a rebuilt from Midwest..... I did the same. (For those on a tight budget, I did some research and I do believe Ind Injection does a credible job).
My Bluechip only has 10,000 miles on it ....... but my CTD has never run better!
Time (and mileage) will verify how wise was my decision to pay a bit more, but I have a good feeling about it!

There's nothing wrong with the design of the VP44. The problem is the lift pump and Dodge's abysmally poor implementation of it.

All of us with FASS, AirDogs, Walbros and Holley Pumps... that still lost VP-44's.... might disagree with you!

There are a lot of vP44 failures with pressure gauge & adequate fuel pressure.
It seems heat kills the electronics in it. I am sure the pump is OK, just the board going south.
Nobody seems to disagree with my numbers and how big this problem is for all Gen 2 owners?
Some rebuilders may do a better job than others, but it seems, unfortunately, to be like a very expensive roll of the dice.
My point is,there seems to not be a good solution.

 

Are there some variants of the VP44 that aren't as good as others? Sure--the ones with the brass barrels instead of steel, and early ones with crappy electronics, etc. Does that make the the basic design of the VP44 crap? Not at all.
