20R fuel pump problem?

My '76 Pickup has been sitting for several months. I had drained the tank to avoid any problems with old gasoline or moisture condensing there. When I went to restart it I needed to pour a small amount of gas directly into the carb. It started fine but I needed to keep it at a fast idle to keep it running. If I let it idle normally it will die immediately and not restart without the pouring of the gas into the carb. Is this a fuel pump problem? The carburetor had been completely rebuilt last year. Any help would be appreciated, I can't very well drive it with my foot on the accelerator all the time.

Start by replacing the fuel filter and see if that helps, if not then check the fuel pump, pull the hose that goes from the fuel pump to the carb off at the carb and put it in a container and crank the engine over to see if the fuel pump is putting out good presure, if it is then the only thing left is the carb, you might need to remove it and give it a good cleaning

A fuel passage in the carb could have gotten gummed up, a gasket could have dried out, the float could be bad, etc.
