I have a 1950 216 six cylinder and im not getting any fuel to the carb. A while ago I replaced the fuel pump and it ran fine. Then, it sat for a while and when i tried to start it again, nothing. I pulled off the fuel line that runs from the pump to the carb and checked it for clogs. it's fine. when i did this fuel ran out of the pump outlet so i guess that the line from the tank to the pump is ok. what do you guys think? I'm stumped.
