I am almost out of ideas! 1967 Camaro,350ci mostly stock with Q-jet. Car starts and idles fine, but under load or if it gets warm it starts to sputter and die. Fuel pressure starts off at 7psi then eventually drops to ZERO! Any ideas? I changed plugs and wires, changed carb, no kinks in line anywhere and just installed a new Holley Blue electrical Fuel Pump (Was Holley Mechanical)also opened gas cap and ran it but still does the same thing.

Sock in the gas tank? I am not sure, do I need to drop the gas tank completely to check? Thanks...

Yeah, it might be worth checking.

Drop tank and remove sender. The sock (strainer) is attached.

I had a similair problem. It was a combo of the sock and the fuel line running close to aheader pipe. I removed the sock ( rather have an easily changed external filter ) and put thermo-cool wrap around the line. In the latter case, I was getting some fuel perculation from the pipe heat.

Also check the fuel line from the tank to the fuel pump along the frame rail. Try disconnecting the rubber lines and blowing air through it to make sure it isn't clogging up with rust.
