Running out of fuel

I don't know. But if you read about ANY service manual from say, 67---7?? or maybe 8?? there's a procedure in them for checking the pump and fuel system. This includes checking the pump with a vacuum gauge, checking the pump for volume. Other than that, you need to start at one end and go to the other


1...Problems with the pickup, including gummed up filter sock, or on some vehicles, the sock has a flat tin bottom which can suck against the tube end

2...Collapsing connector hoses at the tank and the pump

3...Dirt, rust, debri in the supply tubing, or PINHOLES in the line allowing air into the line.

4....Plugged filter after the pump. Don't forget some carbs have filters in the carb inlets.

"Rig" a pressure gauge right at the carb and see what you have
