scheid vp pump help.

1029 Views 7 Replies 5 Participants Last post by  rpainter
Just got done installing a lightning vp pump from scheid on a 2001 stock injectors,lines and crossover tube. Motor is being fed by a fass 150 pump. At idle the truck has white smoke not much but you can see it and smell it but the smoke goes away when the rpm's are raised. Is this normal for the pump?? I have no air in the lines. I am going to pull the injectors to have them tested just to make sure they are ok if it is not normal for the pump to smoke... Also with this truck being a auto will it hurt anything going to .093 tubes??

Doing just .093 tubes shouldn't hurt anything. However, if you were to run .093 lines you would have a serious lack of streetability as the truck would constantly want to die.

:agree2: I have that same pump in my 01 and it did not smoke white at idle until I had an Injector go south on me. I think I would get your sticks tested just to be sure man. :thumbsup:

You will hate the .093 lines. You about have to neutral drop it to keep it from dying.

Drill your pass thru tubes out to .093, youll feel a little difference, and a slight lope in idle, but the driveability is still there.

first, are they stock injectors?

white smoke as in raw fuel white smoke? or as in blown head gasket coolant white smoke?

check your oil for fuel or coolant? check your coolant for oil?

stock injectors yes and no fuel in oil ,oil in coolant or sludge in oil. exhaust smells like fuel similar to my 3rd gen truck but my compression ratio has been lowered to 14.5:1 and this truck is stock compression
