REMOVAL AND INSTALLATION

Push Connect Fittings

 

Push connect fittings for 7.3L diesel systems have two sizes for 9.5mm (3/8-inch) and 7.9mm (5/16-inch) tubing.

Disconnect all push connect fittings from components (sender, six-way valve) prior to component removal. The push connect fittings that connect flexible fuel tubes to the fuel tank sender often cannot be disconnected until the fuel tank (9002) is partially lowered, just before removing the fuel tank completely.

Removal

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

  1. Some adhesion between the seals in the fitting and 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.

  1. 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 about 3.0mm (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.

  1.  CAUTION: Do not use any tools.

    Grasp the fitting and hose assembly and pull in an axial direction to remove the fitting from the tube.

  1. When fitting is removed from the tube end, inspect the fitting and tube for any internal parts that may have been dislodged from the fitting. Any loose internal parts should be immediately installed, using the mating tube to insert the parts.

Installation

  1. It is recommended that the original retention clip not be reused in the fitting. 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). Piloting with an index finger is necessary.

  1. Before installing the 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.

  1. 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.
