I have a weird problem, my lp pressure is 8lb. idle,7lb. crusing, at wot it jumps to 10 or 11 lb. is that the lp? I think maybe! The lp is about 4 months old. it started out at 16lb. at idle and sometimes it does that now?? Could it be electical ?? Help

 

Erratic fuel pressures are a typical sign of a LP that is headed South.

 

Thats what I was afraid of. Do you know how to install a Holley blue back near the tank?

 

I have heard some say that they have had problems with the holleys also. I would go and get something that will not give you any problems so I would never have to deal with it again.

 

Agreed.
I put the FASS II on several months back, and I have never looked Back.

 

My truck was doing the same thing. Was putting on another new lift pump and found out it was sucking air. Put hose clamps on the connection between the steel line from the tank and the rubber line to the lift pump and the problem was solved. DODGE SHOULD HAVE PUT A CLAMP THERE AT THE FACTORY. Just sticking a rubber hose over a steel line is bound to leak after a few years. I'll bet a lot of pumps were sold just for this reason. Ever notice all the aftermarket set up's are clamped?

 

I agree. The "quick disconnects" are an air leak waiting to happen. I took my tank off working on the sending unit and cut those off years ago, and DOUBLE hosed clamped them all. Hose clamps are cheap, being stuck on the side of the road is not.

 

I`ll check that (Now) Thanks I`ll let you know.

 

Gieco 266 You just saved me 200.00 thanks. The connection at the lp from the tank was not seated real good. But I think I will put rubber hose on it from the hard line to the pump so I won`t have to worry about it. Thanks again

 

This was an excellent post, I was seeing goofy pressure reading on my 24v. I was seeing 15+ at startup, then down to 3 – 4 PSI. I was going to swap the LP pump out this weekend, but I put a clamp on the supply line to the LP, PROBLEM SOLVED. It’s stays at 15PSI + if I get on it, it pulls down a few PSI.
Thanks People, you guys saved me $200.00 cash + 2 hours work. I’m hauling a tractor over to Denver next week so I will see for sure how it behaves.
Yep, I'll bet several LP were replaced due too this problem area.
