Fuel Line Coupler: Service and Repair
Fuel Tube/Quick - Connector FittingsREMOVAL
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
Assembling Advice
Immediately install the pipe after applying light engine oil onto pipe for easier assembly. The pipe must be clean of dirt when installing pipe or poor sealing may occur.
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.
TEST/INSPECTION AFTER ASSEMBLING
1. Reconnect the battery ground cable.
2. Turn the ignition key to the "ON" position and listed for pump start-up. Fuel pressure will increase as soon as the fuel pump is actuated. Inspect for fuel leak.
3. Perform step 2 a few times to make sure there are no fuel leakage.
4. Start the engine and observe engine idle speed. The fuel injection system may run poorly if dirt had entered the system during the repair.
