Engine/Transmission (1998.5 - 2002) Fuel Pressure Question

[benhall]

When I start up my truck, I'm getting 13-14 psi but after I start moving and get on the go pedal really good for the first time, it will drop to between 5-8 psi and bounce around everywhere. Is this the first signs of a LP going out? I did the Vulcan big line kit and the relocation kit a month and a half ago and it didn't start doing this until I started into a 500 mile drive. I do have a very slight seep that is coming from a FP port on one of the 90 degree fittings. The seeping fitting is pre-filter and my FP readings are coming from the fitting that goes into the VP.



Thanks for any help,

Ben

Any help? I got the leak squared away, I think.

the stock style LP's stink, not reliable
up grade or carry a spare ,if the LP pushes less than 5psi to the 44 you'll be buying a new VP.

Put your spare pump on and see how it performs! You do carry a spare, right? SNOKING

I had the same problem, unplugged the electric connectors & sprayed with contact cleaner, plugged back in. Fuel pressure would not drop below 8 PSI.
