Default Help with Fuel System Needed

Here are the details. Nasty Nate fuel system with twin intank pumps
with the second pump to come on with boost. Full return system.

When I first hooked the system it would jump up with the key on to 30-40 psi then bleed off. Now when I turn the key on the fuel pressure does not rise it just seems to do nothing. I can hear the pump run for a few seconds but seems to build no pressure.
Ideas?

Swap the pumps using the underhood connectors & see if it does the same thing. I suspect it will.

There is a good chance that the factory quick connect hose inside the tank may have come loose... it is common to not fully connect them when installing the pumps in the tank. They then pop off after a few key cycles.

If you got a dual intank kit for a GTO, it is one of my pump kits, so call me & I'll get you taken care of.
