Fuel Pump: Service and Repair

NOTE: Before installing the pump, it is good practice to crank the engine so that the nose of the camshaft eccentric is out of the way of the fuel pump rocker arm when the pump is installed. In this way there will be the least amount of tension on the rocker arm, thereby easing the installation of the pump.

1. Disconnect fuel lines from fuel pump.
2. Remove fuel pump attaching bolts and fuel pump.
3. Remove all gasket material from the pump and block gasket surfaces. Apply sealer to both sides of new gasket.
4. Position gasket on pump flange and hold pump in position against its mounting surface. Make sure rocker arm is riding on camshaft eccentric.
5. Press pump tight against its mounting. Install retaining screws and tighten them alternately.
6. Connect fuel lines. Then operate engine and check for leaks.
