Installed GFS NO FUEL PRESSURE need help!
I have a 2004.5 that I just installed the GFS-392 kit with the big line kit. I have the quad r/p and fuel pressure gauge. Truck started up fine, and I could hear the pump priming the system up. When I got the truck started I am reading no fuel pressure on the quad. Truck runs great, just no fuel pressure reading. I was getting 5-6 at idle with the stock pump and it would go to 0 when I mashed on it. Now showing 0 all the time. Any ideas?

figured it out. The quad fuel pressure sender has to be grounded to the chassy when you use the big line kit. Works like a charm now and I am showing 15-16 lbs at idle.

I had to edit my post, I meant to say ground the fuel sender unit, not the gauge. Talked with Richard at Glacier and he said this is something he will have to add an adendum to for anyone using the big line kit with the quad r/p and fuel gauge.
