Default Fuel Pressure Issue after Racetronix Install

A few days ago I installed my racetronix 255 fuel pump in my 2006 GMC Sierra (returnless). Install went smooth and everything ran great for 75 miles. Next day, I started the truck to show my brother my exhaust, revved it a few times pretty hard, shut it off. Few hours later I hopped in the truck, jumped on the freeway and everything was fine. Gave it some throttle, and it fell on its face and started to stumble. I limped it home and left if for the night. Next morning I started it, put it in drive and it drove about 40 ft and died. Did this a few times. So I checked the fp at the rail. KO it was about 30psi, KOER, it would creep up to about 50psi, and trickle down to about 20ish and die. Pulled everything apart, and all looked fine, no cracks or breaks in new fuel line (flexible hose from Racetronix) pump was turning and pumping fine from what is seemed and sounded like. Just little to no fuel pressure.

Could I have blown out my stock FPR in the tank? Or is the pump not doing its job after 75 miles? Thanks

I'm going to guess you have a split rubber fuel hose in the tank.

Yeah I pulled it all apart and everything seemed perfect. Nothing cracked or split

Any loose or overheated terminals in the pass-thru connector?

Just an update, the fuel pump went bad. Slapped a walbro in there, everything worked good now.

Did it have a extra small brass fitting at the top of the fuel pump?
