Engine/Transmission (1998.5 - 2002) What does the VP44 have on the P7100?

[Diesel Freak]

I personaly believe VP44 failure rate is directly related to fuel quality. I have 130K miles on my VP44, but I am on my 3rd Lift Pump.

So do you guys think the early VP are weak? If I were to get one, should I jus tap the wire and see if she blows?

 

[DarrellB]

I've got an early 99 (made in May of 98) it has a VP44 with about 100k on it (80k is with the wire tapped), and even has a 53 block.



One day the engine is just going to fall apart I guess. :-laf :-laf

54? I thought 53 was the bad one?

You can cut the wiring harnes out of my truck with a knife and throw the battery on the street and I can still drive anywhere

Yeh - just can't get there as fast or economically...

 

[T. Baker]

Well I'd have no lights but it would run just as fast and get the same milage or better. Might have to roll start it though with no battery. I already had the expirence of loosing all electric power when I lost the main fusable link due to a short. I was on the freeway and the only way I found out I had a problem was I looked down and all the gauges were at 0! So I pulled over when I had a chance but I was driving along just fine. ALL MECHANICAL is the only way to fly for me! I hate to see the future problems you electronic guys are facing when the wiring and plastic in your trucks starts to get old and brittle. I've seen Cummins engines from the '40s that run just fine. I doubt there will be any electonic stuff running in 60 years.

 

[sparks57]

Has anyone ever roll started a cummins? I've never tried... figured I'd break something in the drivetrain.

 

[T. Baker]

Yup. Best to use at least 3rd gear and have some speed otherwise it is going to buck.

Having the comp on a VP44 you can change the setting on the fly from the cab. 7100 you can change just not quite as fast.

The P pump has more pressure (17,000) than the VP44 (14000). On my 97 I can do the same thing as changing settings on a box, using my right foot

As the the question on what is good mileage, well, it is the actual mileage that is really gotten by the tobacco chewing ex-big rig drivers who claim to get 47 mpg uphill pulling a 35 foot fifth wheel.

I read that too, in a recent TDR magazine, so therefore it must be true. I think the article was written by. . . well, lessee, was that Joe Donnelly??

 

[sparks57]

I was under the impression that the VP44 had higher pressures.

According to Bosch:



VE 1250 bar, P7100 1300 bar, VP 1850 bar



or in PSI,



VE 18129, P 18854, VP 26831



Joe?



You care to discuss this further? I'm confused.
