INSTALLATION
1. Ensure garter spring is in cage of male fitting. If garter spring is missing, install a new spring by pushing it into cage opening. If garter spring is damaged, remove it from cage with a small wire hook (do not use a screwdriver) and install a new spring.
2. Clean all dirt or foreign material from both pieces of coupling.
3. Replace missing or damaged O-rings.
CAUTION: Use only the specified O-rings as they are made of a special material. The use of any O-ring other than specified may allow the connection to leak intermittently during vehicle operation.
Lubricate male fitting and O-rings and inside of female fitting with clean engine oil.
4. Fit female fitting to male fitting and push until garter spring snaps over flared end of female fitting.
5. Ensure coupling engagement by pulling on fitting and visually checking to ensure garter spring is over flared end of female fitting.
6. Position retaining clip over metal portion of spring lock coupling. Firmly push retaining clip onto spring-lock coupling. Ensure horseshoe portion of clip is over the coupling. DO NOT install retaining clip over rubber fuel line.

HAIRPIN CLIP CONNECTOR
Hair Pin Clip:
REMOVAL
1. Inspect the push connect fittings for accumulation of dirt. If more than a light coating of dust is present, clean the fitting before disassembly.
2. Some adhesion between the seals in the fitting and the tubing will occur with time. To separate, twist the fitting on the tube, then push and pull the fitting until it moves freely on the tube.
3. Remove "hairpin" type clip from fitting by:
a. Bend the shipping tab downward so that it will clear the body.
b. Spread the two clip legs approximately 3.2 mm (1/8 inch) each to disengage the body and push the legs into the fitting.
c. Lightly pull from the triangular end of the clip and work it clear of the tube and fitting.
CAUTION: Do not use any tools.
4. Grasp the fitting and hose assembly and pull in an axial direction to remove the fitting from the steel tube.
5. Once the fitting is removed from the tube end, inspect the fitting and tube for any internal parts that may have been dislodged from the fitting.
INSTALLATION
1. It is recommended that the original clip not be reused. To install the new clip, insert clip into any two adjacent openings with the triangular portion pointing away from the fitting opening. Install clip to fully engage the body (legs) of "hairpin" clip locked on outside of body.
2. Before installing fitting on the tube, wipe tube end clean with a cloth. Inspect the fitting to ensure it is free of dirt and/or obstructions.
