I am, got a 95gph HPFP kit and it never made more than 18#'s at idle. I dropped the tank to check the suction tube, everything looked good except the screen on the bottom, it was torn so I completely removed it and cleand it all up. I also changed the filter and nothing helped. Now my LP warning light is coming on so I put a guage on it and it's @ 15#'s at idle and when I acellerate hard (like pulling) the pressure drops to the 0 mark and almost rests on the peg. The pump is noisey and has been ever since day 1, sounds rough, not a smooth whine. Yesterday while it was idling in the driveway I fliped up the drain on the water seperator and fuel barely dripped out at all.
This morning with the guage on and @ 15 #'s I flipped the lever on the drain and fuel shot out at a much higher velocity. The problem seems kinda off and on, the pump is running the whole time. It is bad enough where I am not driving it until I get the problem solved. I only have 500 or so miles on my FASS and it's never been quite right. Anyone know anything that might help?
Ive gone over all the connections again and again and everything is good. I do know as soon as I kill the truck the FP hits 0, dont know if its supposed to work that way or not.

 

Just pulled the filter to doublecheck for obstructions and found a few small brass looking metalflakes from what looks like may have comme from the HPFP connections. I dont understand how this could be since I used teflon tape like the instructions suggested.

 

Why were you concerned about it not making more than 18psi??

 

Check your PM's

 

Because the norm for a brand new HPFP seems to be around 20 or better.
It has 500 miles on it and now makes 15 PSI at idle. Even Eric @ Vulcan admitted that was a little low for a brand new FASS pump.

 

We set them to 16-18 PSI on our bench here. 20 PSI is rather high. But we can set it up to 25 PSI if wanted. 15 PSI might be +-% error on gauge or a low spring low pressure as wel do have small +-% error on our springs as well....

 

My FASS 150 came straight out of the box and has put 15 psi to my VP-44 since April of 2004...

I guess things have changed in the last 3 years.

 

x2 Mine has always idled @ 15psi.

 

Anything over 14psi gets bypassed anyway on a VP44 truck......Andy

 

Mines 22 psi at idle but thats pre vp44, never drops below 18.

 

Thanks DD.

 

Well, I ordered an Auto Meter guage and steering column pod to put it in. I'll let you guys know what I get from that guage. My other guage is mainly for a higher FP reading.

 

I put my 95 HPFP on in April, and it put out 16 psi at idle and 15 under load with a new filter. It now has over 5000 miles on the pump and filter, and it idles at 15 and drops to 13 under load.

 

Mine idles between 13-17psi....no issues here.
I think its all a fuel temperature thing.

 

I recently installed the 150/95 on my truck and it worked great the first day the second day I headed for church and it would idle great but when I accelerated it would bogg down really really bad. I thought maybe the Drawstraw II was to close to the bottom of the tank, but after troublshooting approximately 2 hours starting at the tank checking the pressure on the fass pump finding out that it was fine, I realized that I had a kinked line just above the frame rail under the Master Cylinder and it was allowing just enough fuel to start and idle the truck but not to drive it. Just goes to show you that leaving yourself plenty of extra line in case of a problem doesnt allways payoff!!!!
