Check your fuel sock on your sending unit inside the tank.

They can deteriorate and clog up the pickup tube.

Upgrading the pump to the Carter M6907 mechanical might be helpful for better fuel delivery.

Appears the 6907 has gone the way of the Dodo.

Sometimes these smaller retailers have stuff still sitting on the shelves since they do less volume than the big names.

I have one of these pumps (no fuel pressure regulator) feeding my Tri-Ppwer 421 through the stock 5/16” chassis fuel line and it pulls to 5000 rpm (which is as high as it wants/needs to go) no problem. My car has factory A/C so it is equipped with a 1/4” vapor return line.

Stock points ignition system including the coil, always starts with a flick of the key. Distributor was rebuilt and has a custom ignition curve.

A 1968 Firebird should have a 3/8” chassis fuel line if I’m not mistaken.

Yes. I have a 3/8 fuel line from the tank.
