Topic: Fuel Pump
in Forum: C3 Fuel, Emission Control, and Exhaust Systems
Ok the 81 just died and I think it's the fuel pump. I took the air filter cover off to see if fuel was coming out of the carb and I did not see any fuel. Is there a test I could do to ensure that the fuel pump is bad?

You could have a bad pump, or a filter that has stopped up, either at the carb, or the "sock" in the tank.
You can check fuel pump output by taking the fuel line loose from the carb, and running some rubber hose from there into a fuel-safe container, Check the flow while cranking. You can also put a fuel pressure gauge(if you have one) on the line while it's off, and check actual pressure.
If you have good flow there while cranking, the float in the carb may be stuck, or the filter in the fuel inlet to the carb may be completely stopped up.
You say you saw no fuel in the carb, but were you working the throttle when you looked? The accelerator pump will squirt fuel when you work the throttle, but if you're just looking down in there, with the engine not running, you won't see anything.

Not sayin the carb doesn't need some attention, but the problem as I unnerstand it
