Fuel Starvation / Mechanical Fuel Pump

Sorry, dinner and kids.

I have DEI cool tube around the 3/8 fuel line between the fuel pump and the firewall. I don't have any cool tube between the fuel pump and the carb. The fuel lines follow the factory path and are pretty close to the header primary tubes in spots. I have no room for a carb spacer with the current hoodscoop (Cougar Eliminator).

The tank was half full when it first happened today and then full when it happened the second and third time.

The tank is vented and I have a vented cap.
