Disconnect Lines: Carefully disconnect the fuel inlet and outlet lines from the fuel pump assembly. Note their orientation.
-
Disconnect Electrical Connector: Unplug the electrical harness connected to the pump.
-
Remove Old Pump: Unscrew the mounting bolts holding the fuel pump assembly to the engine block. Remove the old unit.
-
Install New Pump: Position the new fuel pump assembly and hand-tighten the mounting bolts. Torque them to the manufacturer's specified value.
-
Reconnect Components: Reattach the fuel lines and the electrical connector securely. Ensure all fittings are tight.
-
Final Checks: Reconnect the battery. Prime the fuel system by turning the key to the 'On' position a few times. Start the engine and carefully inspect for any fuel leaks around the connections.
