Hairpin Clip Fitting

REMOVAL
1. Inspect visible internal portion of fitting for dirt accumulation. If more than a light coating of dust is present, clean the fitting before disassembly.

NOTE: If necessary, drain fuel tank.

2. Push connect fittings are designed with a retaining clip. The fittings used with 9.5 mm and 7.9 mm (3/8 and 5/16 inch) diameter tubing use a hairpin clip. Clips should be replaced whenever a connector is removed. 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 clip from fitting by first bending the shipping tab downward so that it will clear the body. Next, (using hands only) spread the two clip legs about 3.2 mm (1/8 inch) each to disengage the body and push the legs into the fitting. Complete removal is accomplished by lightly pulling from the triangular end of the clip and working 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.

NOTE: On 90 degree elbow connectors, excessive side loading could break the connector body.

5. After disassembly, inspect and clean the tube end sealing surface. Tube end should be free of scratches and corrosion as these result in paths for fuel or vapor leakage. Inspect the fitting and tube for any internal parts such as O-rings and spacers that may have been dislodged from the fitting. Replace any damaged connector.

INSTALLATION
1. Install new connector if damage was found. Install 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). Piloting with an index finger is necessary.
2. Before installing fitting on the tube, wipe tube end with a clean cloth. Inspect the inside of the fitting to make sure it is free of dirt and/or obstructions. Apply a light coat of clean engine oil meeting Ford specification ESE-M2C153-E to the tube end for ease at assembly.
3. To install the fitting onto the tube, align the fitting and tube axially and push the fitting onto the tube end. When the fitting is engaged, a definite click will be heard. Pull on fitting to ensure it is fully engaged.
