Fuel Line Coupler: Service and Repair

REMOVAL




1. Open the fuel cap to relieve the fuel pressure in the tank. Use compressed air to blow off any dirt when disconnecting the fuel quick connect fittings.

Cover the connectors with a cloth when disconnecting the piping to prevent fuel spray, in case of any existing fuel pressure in the system.




2. For removal of the quick connector, hold the quick connector in one hand, and pull out the connector with the other hand while pressing the square relieve button of the connector, as illustrated.






NOTE: Do not use tools of any kind. Only use bare hands when disconnecting the connector. Use a lubricant (light oil) and/or push and pull the connector until the pipe is disconnected. Cover the connectors with a plastic bag after disassembly to prevent dirt and water from entering.

Reuse of Quick-Connector




- Replace the port and connector if a scratch, dent or crack is found.
- Clean the fuel pipe of any dirt particles before installing. The Pipe end must be free of defects (i.e., scratch, rust and dent) before fuel pipe installation or poor sealing may occur. Replace the fuel pipe if damaged.
- After cleaning the pipe, insert it straight into the connector until it clicks. After it clicks, try pulling it out to make sure that it is not drawn and is securely locked.
