Access the fuel pump – Remove the rear seat cushion to access the fuel tank access panel. Unscrew the retaining bolts and carefully lift the panel. Disconnect electrical connectors and fuel lines – Gently unplug the electrical connector and disconnect the fuel inlet/outlet lines using a fuel line disconnect tool. Remove the old pump assembly – Unscrew the mounting bolts and lift out the old pump. Note the orientation of the fuel filter and O-rings. Install the new LFJB-13-35X – Place the new pump into the tank, aligning the O-rings and ensuring the fuel filter is properly seated. Reattach the mounting bolts. Reconnect all lines and connectors – Reattach the fuel lines and electrical connector. Double-check for leaks. Reinstall the access panel and seat – Secure the panel and reposition the rear seat. Reconnect the battery and test – Turn the key to the ON position (without starting) to prime the system. Start the engine and monitor for unusual noises or leaks.
