Fuel Line Coupler: Testing and Inspection

FUEL TUBE/QUICK - CONNECTOR FITTINGS

Assembling Advice
Application of engine oil or light oil to the pipe facilitates connecting work. The work should be started immediately after lubrication, since dust may stick to the pipe surface to cause poor sealability if a long time passes after lubrication.

Test/Inspection After Assembling
1. Reconnect the battery negative cable.
2. Turn the ignition key to the "ON" position and check pump startup sound. As the pump is actuated to raise fuel pressure, check and see fuel leak from the piping system.
3. Make sure of no fuel leakage by conducting the above fuel leak check a few times.
4. Start the engine and make sure of stable idling speed and normal vehicle run. The entry of dust during the work may sometimes affect the fuel injection system.
