REMOVAL
CAUTION:
^ DO NOT ALLOW SMOKING OR THE USE OF OPEN FLAMES IN THE AREA WHERE WORK ON THE FUEL SYSTEM IS TAKING PLACE. ANYTIME THE FUEL SYSTEM IS BEING WORKED ON, DISCONNECT THE NEGATIVE BATTERY CABLE, EXCEPT FOR THOSE TESTS WHERE BATTERY VOLTAGE IS REQUIRED.
^ WHENEVER FUEL LINE FITTINGS ARE LOOSENED OR DISCONNECTED, WRAP A SHOP CLOTH AROUND FITTING AND HAVE AN APPROVED CONTAINER AVAILABLE TO COLLECT ANY FUEL.

1. Grasp both ends of one fuel line connection and twist 1/4 turn in each direction to loosen any dirt in quick-connect fitting.

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.

4. Pull the connection apart.

INSTALLATION

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-RING 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.

NOTE: Do not attempt to straighten the kinked nylon fuel lines. Replace any kinked nylon fuel feed or return lines 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.
