Tapping for fuel pressure reading (Post Liftpump)

[LBZ]

Larry I just realized LLY are different than lb7s
there is a hose that comes off to the left off the shrader valve,Im thinking its a 12mm or 1/2" hose possible 3/8s but all you you have to do is T into that hose I followed it down and it sits around the FICM

I think that would work just fine


Also here is a pic of my filter housing with the o-ring fitting,Carefull not to look at it to hard as it will fall off:rofl:

Clean your motor!!

I like the idea of tapping into the fuel filter base-I may have to try this.

motor is clean,filter housing is dirty

Is this piece trick or what

Tony Burkhardt fixed me up a fitting so I can hook my Fuel pressure gauge up to the test port near the alternator.

nice. What a novel idea.
Mine's been sitting for about 3 months since I got it from Tony, waiting for my gauge and what not. Hope to have it hooked up soon.

I do owe the tip on finding this fitting to Ted though

No problem buddy, I was just messing with you. I hope all goes smooth in replacing the fitting on the test port.
Good luck and keep us posted.

I'll get right on it, as soon as the coffee takes affect

What is that fitting? how much?

 

[LarryJewell]

Very simple to do, I sprayed the fitting with PB blasters twice yesterday while the motor was hot and once this morning while it was cold. It instantly broke free with a crescent wrench. The longest part of the install was fishing the wire back from the liftpump and securing th wiring where I wanted it in the motor compartment. Turned the truck on and it works

Tony Burkhardt fabbed it up i'm guessing, the threads looked freshly cut.

Just a quick run and it doesnt take much throttle to pull the guage down to 5psi , it idles at about 7psi...............Before I took it off the Fass it was showing that the Fass was putting out a steady 8-9 psi.

All new filters on the Fass and factory filter. Guess its time for a bigger lift pump, probably will go with the Airdog 150/150 My current pump is a 4 year old Fass 150/95.

Anybody using this pump, what do ya'll think about it.

I'm using the Airdog 150 and it seems to be doing real well. I have 1 pull that I logged and it maintained a steady 25k. I'm not sure where the low pressure side is at right now. My next step is get a fp gauge so I can watch that also.

Its shimmed and ported

I dont have trouble maintaining rail pressure, I do wonder how though since I'm pulling the gauge so far down. WOT on a 2800 PW and I pulled the gauge down to 3 psi

 

[2500HeavyDuty]

i mean the fass

 

[LarryJewell]

I didnt know we could shim the Fass

you can shim the airdog, just add a few shims to the return line behind the spring to ass pressure or swap out the spring.

FASS should have a similar set up inside the pump i think
