The fuel lines in your Ford Ranger, equipped with the 2.9-litre engine, are connected to the fuel injector rail using a quick-disconnect fitting that uses multiple O-rings to seal the connection. Over time the O-rings wear out and replacement O-rings must be installed. Disconnecting the fuel line from the fuel injector rail requires a special tool that expands the locking device inside the connector so that the two components can be separated.

Things you need
- Ford fuel line tool
- Spray bottle
- Soapy water
Relieve the fuel pressure from the fuel system by removing the fuel pump fuse in the fuse block located in the engine compartment. Start the engine and allow it to idle until it stalls. Turn off the ignition key and reinstall the fuse.
Lift up on the metal retainer that is snapped over the quick-connect fitting and slide it off the fuel line. Clean any accumulated dirt and grime from the quick-connect fittings using a spray bottle filled with soapy water and a toothbrush. Scrub gently around the connection to remove deposits from inside the locking mechanism.
Snap the Ford fuel line tool onto the fuel line and push it firmly into the locking mechanism until you feel it expand the spring lock inside the fitting. Twist and pull on the flexible fuel line until it slides from the fuel rail. Remove the tool from the fuel line.
Tips and warnings
- Wear safety glasses and work gloves when working on the fuel system to prevent serious injuries and skin irritation caused by spilt fuel.
