changed vp trying to find miss but sounded same after installing one of chips from blue chip. use lucas about 85% of the time. lost the first lift and vp before guages were installed. after install on the way to MO fuel pressure was down to 0. got to MO changed lift pump but never had any problems with vp. ???

 

one vp-44 @ 40K
now 1 l.p.( maybe 2 if you count the cause for the 1st vp-44)

using power service for the last 30k miles 104,000 miles on the truck.
had used additive occationally before. but not `till after the new injector pump.
now i use it every tank!!

 

No failures - ever - 150,000 mi

Have never put a drop of additives in the fuel (but I also only use major branded fuels - Chevron, Texaco, Shell)

 

1 lp, 2 holley blues, and 2 injection pumps

 

with or without additives?

 

1 lift pump changed under warranty at about 100,000kms, had VanAaken towing module on also since day one. Put FASS on at 150,000kms. I have about 230,000kms now, still with original VP-44. I have used Powerservice with Lubricity additive since I bought truck new in May 2000. Also add 4-6 ozs low ash 2 stroke oil every tank. I never run below 1/2 tankfull if I can help it.

 

2001 0VP 1LP fuel treatment every fueling, 89K

 

changed to FASS after lp issues, may still need IP. Problems started with in 2,000 miles of first using addative. Bought truck with 120,00 miles so unsure of previous additive history. Rarely use additives now but was using for every other tank.

 

Lucas since new = 1 LP at 9,950 miles and no VP44 failure to date. The LP worked but did not maintain proper pressures. Apparently caught it just before it went completely out. I'm glad I had a pressure guage.

Not too much driving on this truck though. Truck only has 20,135 on it.
