The fuel system, depending on model year of the vehicle, may be equipped with push type connectors or spring lock couplings. When removing the fuel lines on these vehicles, it will be necessary to use Fuel Line Coupling Disconnect Tool D87L-9280-A or-B, or equivalent.

Quick-Connect (push) type fittings must be disconnected using proper procedures or the fitting may be damaged. Two types of retainers are used on the push connect fittings. Line sizes of3/8in. and5/16in. use a hairpin clip retainer.1/4in. line connectors use a Duck bill clip retainer.

Push Connectors and Spring Lock Couplings

See Figures 3 and 4

If the fuel system is equipped with spring lock couplings, remove the retaining clip from the spring lock coupling by hand only. Do not use any sharp tool or screwdriver as it may damage the spring lock coupling.

  1. Twist the fitting to free it from any adhesion at the O-ring seals.
  2.  

Inspect the condition of the O-ring seals and replace them with the correct parts if necessary.

  1. Fit Spring Lock Coupling Tool D87L-9280-A/B or equivalent to the coupling.
  2.  
  3. Close the tool and push it into the open side of the cage to expand garter spring and release the female fitting.
  4.  
  5. After the garter spring is expanded, pull the fittings apart.
  6.  
  7. Remove the tool from the disconnected coupling.
  8.  

Hairpin Clip
  1. Clean all dirt and/or grease from the fittings. Spread the two clip legs about an 1 / 8 in. each to disengage from the fitting and pull the clip outward from the fitting. Use finger pressure only, do not use any tools.
  2.  


CAUTION
Never smoke when working around gasoline! Avoid all sources of sparks or ignition. Gasoline vapors are EXTREMELY volatile!

  1. Grasp the fittings and hose assembly and pull away from the steel line. Twist the fitting and hose assembly slightly while pulling, if necessary, when a sticking condition exists.
  2.  
  3. Inspect the hairpin clip for damage, replace the clip if necessary. Reinstall the clip in position on the fitting.
  4.  
  5. Inspect the fitting and inside of the connector to ensure freedom of dirt or obstruction. Install fitting into the connector and push together. A click will be heard when the hairpin snaps into proper connection. Pull on the line to insure full engagement.
  6.  

Duck Bill Clip
  1. A special tool is available for Ford for removing the retaining clip (Ford Tool No. T82L-9500-AH). If the tool is not on hand see Step 2. Align the slot on the push connector disconnect tool with either tab on the retaining clip. Pull the line from the connector.
  2.  


CAUTION
Never smoke when working around gasoline! Avoid all sources of sparks or ignition. Gasoline vapors are EXTREMELY volatile!

  1. If the special clip tool is not available, use a pair of narrow 6 in. (152mm) locking pliers with a jaw width of 0.2 in. (5mm) or less. Align the jaws of the pliers with the openings of the fitting case and compress the part of the retaining clip that engages the case. Compressing the retaining clip will release the fitting which may be pulled from the connector. Both sides of the clip must be compressed at the same time to disengage.
  2.  
  3. Inspect the retaining clip, fitting end and connector. Replace the clip if any damage is apparent.
  4.  
  5. Push the line into the steel connector until a click is heard, indicating the clip is in place. Pull on the line to check engagement.
