NEED YOUR HELP **statistics on VP44 failure**
Hey guys I'm doing a real statistical analysis on VP 44 failure, so the more responses I get the better. Has your VP44 failed? If so there are 4 criteria:

On this one I need all the help I can get. My hypothesis is that when using parts (e.g. banjo fittings and bigger injectors) with no subsequent pressure increase between the VP44 and the injector; the pump is subject to destroying itself due to a lack of fuel pressure between those two points. Thanks again for all the help.

Stock as a Rock.
VP died 3 months and 4,000 miles after I bought it brand spankin new, never even test driven before me, off the lot.
Still have the same lift pump putting out 15 idle, 10 at wot.
No codes ever thrown.

Basicly I'm looking at anything between the pump and injectors that would increase the flow of fuel. But for the study I have to, for practical reasons, trim the choices down to 4. I chose the 4 I did because those seem, at least from my vantage point, to be the modifications that pop up most often between the VP44 and the injectors. Scott

Do you also want to know if they haven't failed? If so I am still on the original LP/VP with 35000 on the clock. Bombed from day 1 (however not at the current level).

Don't think the poll will help you much anyway as most folks have a stock system and thus more occasions for failure.

there was a thread on here 6 mo ago?? he knew how to take these apart and back again..it is the electronic thingy rotator assy? that measures the fuel that fails.......nothing todo with the pump.........The newer the pump the less chance of a dump
For instance, my whole eng took a dump (but thats a an other story)- and I have the same pump with drilled out banjos and 275 inj........nothing wrong with pump so far....................
