I am trying to fire up my car with a mid-seventies 440 in it but am having trouble getting fuel to the carb. I am thinking that the fuel pump is bad. I installed it properly over the push rod but when I crank the engine, I am not drawing any fuel. I tested it by putting a small amount of fuel into the reservoir cup of a one man brake bleeder which has a clear hose about 8" long. When I tried this test with the pump out of the car and pushing on the pump arm by hand, it drew fuel. When I installed it in the engine, it does not. I pulled the plug under the pump, saw that the pump arm was properly over the push rod, I then checked the travel of the pump arm using a tape measure and a digital camera so I could get a good look at the results. It appears that the travel length is about 1/4" total. Is this the correct amount of travel for the pump to work? I am sure I pushed the pump farther than that when I pushed it by hand. I need to find out if I am still not doing or assembling something right or if the pump is shot and needs to be replaced. Also, when I rebuilt the carb, I filled the bowls with fuel. The engine ran for about 5-10 seconds but the pump still did not seem to draw any fuel but it was attached to the regular fuel line to the tank at the time. I have blown out the fuel lines with compressed air as well.
