Default VP44 problems - Getting tired of the BS!
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. 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 )
  • Fuel pressure of >14 PSI (Raptor pump and no lower than 16 PSI )
  • Filters of <10 Microns
  • Little to no water (We all know farm fuels get water from time to time from sitting in the weather )
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...

Agreed , My VP44 is brand new and as long as I keep it over 10 psi in fuel its happy ... but I keep it at 18psi WOT AND 21psi idle ... raptor 150 lift pump .... so its happy .

Sounds like the OP needs to take care of the VP44 with a good lift pump and most of all a good filter . I use a Amsoil filter witch is a Donaldson

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.

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...

Another update to this I found that bad alternators can and will causes P1688, P1689, and a few other failures of the VP44. So there is more to watch over to protecting your VP44.
