  5. Install Electrical Wiring:
    – Connect the power wire to the positive terminal of the pump.
    – Run a ground wire to a solid metal point on the RV chassis.
    – Follow the wire diagram that comes with your pump, as specific connections may vary by model.

  6. Add a Relay: Install a relay in line with the pump to manage electrical flow. This protects the circuit by reducing wear on the power switch.

  7. Test the System: Reconnect the battery and turn the ignition to the “on” position without starting the engine. Listen for the pump to prime. Check for leaks in all connections.

  8. Start the Engine: Once you confirm no leaks, start the engine to ensure the pump operates correctly. Monitor for unusual sounds and check fuel delivery.
