Fuel Line Coupler: Service and Repair
Hairpin Clip Fittings
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. 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 first bending the shipping tab downward so that it will clear the body. Next (using hands only) spread the
two clip legs 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. The use of tools may cause a deformity in clip components which may cause fuel leaks.
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 this could 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 to the tube end for ease of 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 make sure it is fully engaged.
