REMOVAL & INSTALLATION
The fuel pump is mounted on the side of the engine and is driven by an eccentric on the camshaft.
If the engine is set with No. 1 piston at top dead center, the eccentric pressure on the fuel pump arm will be reduced, thus making removal and installation easier.
- Remove the air cleaner, heat duct and, depending on model, any other component interfering with pump removal. Remove the plastic pump shield, if equipped. Disconnect the fuel lines (plug the line from the fuel tank).
- Remove the two mounting bolts or nuts and remove the fuel pump. Remove the gasket and insulator.
- Clean all pump mounting surfaces.
- Apply a non-hardening sealer to all gasket surfaces. Place the fuel pump into position and secure it with the mounting bolts or nuts.
- Connect the fuel lines. Install the plastic shield on models equipped, and all other components removed.
Disconnect the fuel line from the carburetor and attach a pressure tester to the end of the line. Crank the engine. The tester should show psi as listed on Tune-Up charts.
