Caution: Wear safety glasses when using compressed air in order to prevent eye injury.
2. Use compressed air in order to blow out dirt from the quick-connect fitting.
3. Squeeze the plastic release tabs.
4. Pull the connection apart.
Installation Procedure
Caution: Always apply a few drops of clean engine oil to the male pipe ends before connecting fuel pipe fittings in order to reduce the risk of fire and personal injury.
This will ensure proper reconnection and prevent a possible fuel leak.
During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated.
1. Make sure that the connectors are clean.
2. Apply a few drops of clean engine oil to the male connector ends.
3. Push the connectors together in order to cause the retaining tabs/fingers to snap into place.
4. Once installed, pull on both ends of each connection in order to make sure that the connection is secure.
Notice: Do not attempt to straighten the kinked nylon fuel lines. Replace any kinked nylon fuel feed or return pipes in order to prevent damage to the vehicle.
5. After you connect all of the lines, crank the engine for a few seconds (turn off the engine if the engine starts). Then, check for any fuel leaks.
