If you plan on big power, might as well bypass the FPCM with a Walbro and a hotwire kit. The PCM can be setup to receive constant voltage instead of the variable.

Good call on that. Still going to have to do a hotwire to bypass the FPCM. When I had all the issues on my 08, that was the only real option.Originally Posted by CHEVROLADE

GSS340, same as the NBS and OBS.
The pump you are looking at getting is PN 027-11140 on Jegs. I doubt that comes with any wiring. The hotwire kit is literally two wires, but whatever floats your boat man. I want you to get the 340 and tell me how it turns out. That is the pump I plan on using when I need more fuel.

there's a little more to installing a fuel pump and making the ecm happy with no fpcm and have no ses lights.
we can actually remove the fpcm completely and make the ecm happy with it.

Change voltage to constant instead of variable and wire the pump in? I did it with no hassle.

talking about removing the fpcm completely, does your truck still have it?

On my 08, I left the FPCM in the truck, but replaced the pump with a Walbro. Since my 08 had a variable voltage pump, I changed the pump setting in the PCM to constant and set a voltage that met the pressure I wanted. I was running 70-75 psi if I left it at the stock voltage. I bumped it down a little and settled it at 65, then reset my fuel tables to match. Unless you are converting to an aftermarket regulator, the FPCM needs to stay in, just be changed in the PCM.

the few we've done, we installed aftermarket regulators due to the build requiring them, so we dumped the fpcm.
