Engine/Transmission (1998.5 - 2002) IN-Tank Lift Pump or Not

[dclassens]

Truck received a new intank lift pump and VP44, and should be done Wednesday(5/22) night. Worried that the intank has just as many issues along with dropping tank every time. Like the idea of fuel cooling the pump like a chevy gets. Any feed back would be great. truck will never get to a higher power level than an EZ and some Low end Sticks. I have an idea what kind of feed back I will hear(I made a bobo) but still curios. Thanks

Is this a warranty job by DC, why the intank pump? SNOKING

Local diesel shop said this was the best way to resolve this problem for good. This comes with a one year warranty I believe. Not a whole lot of options and I NEED the truck ASAP.

I dont think this is a once an for all fix. there have been failures already with this setup. despite all the problems with the carter,moving it back by the tank will extend its life . the main thing is it is easy to change on the side of the road. if you have gauges it will let you know before it fails. I am on my 5th. 2 since move back near the tank. thats 4 in 447590kms. still on the original vp-44. my 2 cts.

Definitely NOT! Especially if you plan to do any mods to your truck. The intank is limited in flow capacity. There are plenty of options available, the least of which is a Carter replacement relocated to the frame. I don't recommend this since the pump has major design issues and will never work the way it should, no matter what you try. You could go Glacier Diesel GFS-392 or belt driven pump, FASS, Airdog or rasp belt driven.

Do a search on the intank pump and read up. The stock LP is a better deal even on the engine, but much better on the frame rail. If you want to spend more money there are many choices. SNOKING

There are a couple of threads about what the VP44 NEEDS.



13. 5 psi, lots of volume, clean, water free, cool fuel.



I think the in tank pumps are very very very short in the psi department.



The fix seems to be a higher psi pump with some sort of flow bypass to control the psi the Vp44 actually sees, with LOTS of volume. Then make sure you have good clean ... fuel.



IF you have the intank pump and you have to work on it for any reason it is going to be more difficult than crawling under the frame and changing a pump mounted on the frame (or where ever) that is relatively easy to get to. I can guarantee you that you will sometime in the future you will need to do something with the pump (replace it, clean it, adjust it, electrical contacts, something).



BUT, it is YOUR truck, so take your best shot,
