Fuel Pump Replacement: A How-To Guide
The mechanical fuel pump provides fuel to the carburetor and is actuated by an eccentric on the camshaft through the rocker arm or push rod. When you replace a fuel pump, you should also install a new fuel filter. Check the fuel line running from the fuel tank to the pump, and replace it if it’s cracked or leaking. If you replace the fuel line, you should also install a new hose.
