1985 Ford 150. It runs for a few minutes. It then quits. It sounds like fuel starvation. The tanks are full. The clear fuel filter before the mechanical fuel pumps looks empty when truck dies.

Get a pressure gauge to determine your fuel pressure.

Should I check the pressure between the mechanical pump and the carb? It has one solid metal fuel line there. I wouldn't want to cut that line.

Has anyone heard of the fuel tank selector device failing before? I could see it getting stuck on one tank, but stopping all fuel seem kinda odd.
