Engine/Transmission (1998.5 - 2002) VP-44 failures AFTER pusher install?

Sorry Gary....

Well waddaya know - a full week and *19 posts* - and STILL no VP-44 failures reported

I personally know of two guys here in the NW that have had injection pump failures, and yes they had pusher setups.



Both guys are well known among the boards/members, so I'm not going to post their names because there must be some reason they didn't do it themselves.

Without specifics - had they had a LP fail prior to the pusher install that may have contributed to the failure, etc. , 2nd hand, anecdotal info is sorta worthless - God knows, PLENTY of fellas have stood up in the OTHER non-pusher VP-44 failure threads and polls...



The fact we have so far seen NONE here in the 2 weeks THIS thread has been running should reveal SOMETHING of significance...

Let me expand on the above a bit...



IF a fella had a vehicle, didn't check the oil - and one day the engine starts LOUD knocking and the oil light come on - and he stops, finds the oil WAYYyyyy low, so adds some. THEN, the engine SEEMS OK, oil light is off - so he next decides to switch to Amsoil or Mobil 1 synthetic... Few thousand mile later, engine is smoking, and starting to get VERY noisy - was his "problem" caused or related to the synthetic - or because he ran it outta oil previous to the switch?



SAME is possible with the pusher pumps - IF a fella has been running his truck with no guages for 20-30,000 miles, then finds he has a bad LP that MAY have been bad for MANY of those miles, merely THEN adding a pusher is NO gurantee that sufficient wear/damage has not ALREADY been done to the VP-44 to contribute to an early failure... And to THEN assume the pusher was a worthless effort is hardly reasonable...



As far as I am concerned, the basic, primary contributor to early VP-44 failure is lack of needed lubrication due to reduced amounts in current diesel fuel - that is aggravated if/when a failing LP starves the VP-44, making it work harder with even LESS fuel - and added power enhancements sure don't help - although fellas adding those usually add guages at the same time.



SO, what to do as SOON as possible to insure maximum VP-44 life?



1. Add a good diesel lubricant to your fuel.

2. Add a pusher, or similar, pump to guarantee maximum need fuel supply and lubrication.

3. GET GUAGES to monitor fuel pressure/flow



Do ALL those BEFORE you have any fuel delivery problems - not AFTER - and you will have done the most you can to assure maximum VP-44 lifespan!

I did a pusher and a prefilter to keep all the parts clean, the filter also has a water separator so no water gets into the pumps.



There is a one-way valve with a bypas in case the pusher fails, and I have a sensor that tells me when there is water in the filter and when the filter needs to be replaced.

So far with my guages, all is normal. I use filtakleen additive every fillup.

EricBu12- where did you get the one way check valve? I have been looking for one
