VP44 problems - Getting tired of the BS!

Recommended Posts

Ok first of let me vent here a second... (You've been warned!)

I got a phone call from a gent this evening upset at his truck because of hard starting and P1689 error code randomily coming. He admits he's got a Raptor fuel pump, Edge Juice and 100 HP injectors. That fine... But the admits he's selling it because he's tired of all the VP44 failures and problem.

WHOA! Stop the train... This is where I'm getting really tired of people giving the VP44 a bad name now pay attention.

Now I asked him of his source of fuel. His response is he's running red dye fuel from a farm tank because its free.

Then ask him of the the fuel filter he's running. His response is a cheap wix/napa filter.

So now whining about VP44 failures but he's feeding it dirty watered down fuel and using cheap filters and wonder why the VP44 are not lasting. rolleye0011.gif VP44 injection pump are a great pump and work very very well only if you feed them right...

  • Fuel lubricity of <450 HFRR (He admits in using 2 cycle oil happy0159.gif)
  • Fuel pressure of >14 PSI (Raptor pump and no lower than 16 PSI happy0159.gif)
  • Filters of <10 Microns
  • Little to no water (We all know farm fuels get water from time to time from sitting in the weather rolleye0011.gif)

So what I'm finding out is people are abusing the pumps by cheating and then blame the pump for the poor quality of fuel and filters used. I'm really getting sick and tired of all the VP44 bashing... mad0137.gif

When I was in high school many moons ago learning GW-BASIC and Pascal programming languages, my teacher told me one thing that has stuck with me all these years:

Garbage in, garbage out.

While the VP44 was meant to be a temporary solution for emissions so the HPCR could be developed, it was still a good pump. However, if you're not picky about your maintenance, fuel source, types of oil you use, and filters ...... you don't need to be behind the wheel of a diesel, much less own one.

Isn't that the truth!! It holds true with a lot of things actually. . . .

It doesn't take a 'rocket scientist' to look at this filter spread sheet and see exactly which filters are better than others. Then you just assemble what you like or need for your purpose and run with it. I am seriously thinking about putting a 2 uM on the '92. I know it doesn't need it but it sure won't hurt it either! Course I may look into adding a little used motor oil into it's 'diet' also so then I would feel a lot better with a 2 uM fuel filter in the system.

After all the time of hearing VP44 failure and how bad VP44 pump are... I now know what every VP44 rebuilder is fighting every day. Where VP44 owners are cutting corners on fuel quality and filters and feed it dirty nasty fuel from gawd knows where.

Why is that you here the same guy bragging about AMSOil in every hole but feed the fuel tank with worse garbage he can find? Why is this? Then blame the VP44 for being a $hitty pump. rolleye0011.gif

I'll admit there is a few actual short life span pump that failed premature but not as often as the big forums as pushing it... fing03.gif

What think makes you think pump fuel is any better than red fuel.


One looks like green cow piss one red

Red dye and highway diesel comes from the same tap. There are produced the same. So the HFRR score is the same. The only thing they do is add red dye to the fuel make it off road fuel for tractors and equipment. Basically, the only difference is the price.

Remember tax evasion is a FEDERAL crime. Last time I heard its a $1,000 per gallon of fuel in the tank for a fine in Idaho.


I've heard all the dumb reasons on using red dye fuel to being cheaper in price, to the HFRR score was better (not true), more BTU and better MPG on red dye (again not true). The stories and BS I've heard about using red dye crazy.

      If you are ever searching for a filter, here are a couple of handy tools!!
      Wix makes great filters! Their site has come a long way and is very helpful in several ways:
      Wix Vehicle Filter Look Up - Shows just about every filter on a rig!
      Wix Home Page Filter Search - Type in any Filter Number for a Wix Cross Reference! - What I like about this is if you then click on the number it shows, a popup will show all the specs for that filter. Very handy when you are trying to find a different sized filter.
      And if you are trying to find the number for any brand of filter from just about any brand that you currently have the number of:
      Oil Filter Cross Reference
      These tools should get you on your way to finding the correct or better filter for whatever you are working on!!!

      While I was out on my camping trip and hauling around my 31' Jayco Eagle Travel Trailer I had some weird fuel pressure problems occuring. Start up cold and get 17.5 just about 18 PSI at a idle and then pull the grade up to New Meadows, ID still holding 16 PSI which is normal and fine. But now as the day got hotter and we got down around Council, ID the pressure fell off to 12.5 at WOT and idled at 15 PSI. Hua??? While I was stopped the at one place I played with bumping the starter and you can see 17-18 PSI and then hear a change in pump pitch and the pressure fall again to 15 PSI. It's like the check ball is hanging up again. So I'm going to pull it back apart and double check again. So later on down the road I pick up fuel I figured I add a extra few ounce of 2 cycle oil than typical. Well the pressure went right back up to normal 17-18 PSI at idle and remain normal the rest of the day with no problems.
      (Enjoying our camping)
      Now hitched back up early morning and started my way back out of Lowman, ID and got good strong fuel pressure. But by the time I got to Banks, ID the fuel pressure was starting a to fall again. It went back down to the 12-15 PSI range again. On a few other stops I play again with bumping the start and sure enough yo can see 17 PSI for a burst of a second or two and then falls with change of pitch of the pump. I wondering if the fuel temperature is effecting the check ball and spring some how that its not working properly? Because with cold fuel its working fine but as a soon as the fuel warms up it sinks in pressure?
      Yes... I got a fresh set of donaldson filters on my truck and no change with that...
