Thank you for the reply, Here is some more information. The release tools can be purchased at your local auto parts store, like Auto Zone for example.
MFI engines use Teflon® stainless steel for fuel supply and return lines and carbon steel for vapor line in the engine compartment. Outside the engine compartment the materials are either nylon (Aerostar and Ranger), or Teflon® stainless steel for fuel lines and carbon steel for vapor line (Explorer).
On Aerostar, the plastic fuel tube assemblies are secured to the body rails with nylon wraparound clips and push-in pins. The clips are located along the tube assembly by upsets on the fuel tube. On Ranger vehicles, the plastic fuel and vapor tube assemblies are secured to the frame rails with integral clips.
On Explorer vehicles, the steel fuel and vapor tube assemblies are secured to the frame rails with integral clips.
Spring Lock Coupling
Fuel tubes which connect to MFI engines utilize spring lock couplings in the engine compartment instead of the plastic or stainless steel push connect fittings. The spring lock couplings work by insertion of the fitting's male end, which is surrounded by two O-rings, into a female flared end engine fitting. The coupling engagement is secured by a garter spring which prevents the female flared end from becoming disengaged from the male end.
Spring Lock Coupling Disconnect Tool D87L-9280-B or equivalent is used to disconnect the 12.7mm (1/2-inch) spring lock coupling supply fitting. Tool D87L-9280-A or equivalent is used to disconnect the 9.52mm (3/8-inch) spring lock coupling return fitting.
