1990 Ford Ranger Disconnect Fuel Lines
The fuel lines on your 1990 Ford Ranger have three different types of connectors. There are R-clip quick-release couplings, which can be identified by the two tabs extending out of the connector. Push-connect quick-release couplings have square openings in the coupling. And spring-lock couplings are used to connect the fuel lines attached to the fuel rail. The spring-lock couplings are more complicated than the others and require the use of a spring-lock coupling tool to disconnect them.

 Disconnect Fuel Lines
- Wipe the coupling to be disconnected with a clean rag. Identify the type of coupling and then disconnect as described.
- Disconnect an R-clip quick-release coupling by either spreading out or squeezing in with your hand on the legs of the clip so it can be moved. Then push the U-shaped portion of the clip out of the coupling. Pull straight out on the coupling with your hand to disconnect the fuel line.
- Disconnect a push-connect quick-release coupling by squeezing on the white locking tabs using needle-nosed pliers while pulling the fuel line off with your other hand. The locking tab portion of the coupling will remain on what the fuel line was connected to.
- Disconnect a spring-lock coupling using a spring-lock coupling tool. Be sure you obtain a tool of the correct size for your fuel line. Remove the safety cover over the coupling with your hand. Install the spring-lock coupling tool on the coupling. It will only go on in the proper direction. Push the tool with your hand firmly toward the garter spring -- a metal loop -- to remove the garter spring from the female flared end of the fuel line. Keep the tool in that position and pull the coupling apart using your hands. Remove the tool and complete the disconnection.
 Tips & Warnings
- Remove fuel lines from the parts they connect to before loosening the part.
- Inspect the coupling before reconnecting it to insure there is no damage.
- You may need to replace the fuel line if a coupling is defective.
- Gasoline is a highly flammable material. Perform the disconnects in a well-ventilated area without a source of combustion. Keep rags handy to clean up the gasoline that comes from the fuel lines and have a fire extinguisher available.
- Always depressurize the fuel system before disconnecting a fuel line.
