• Description:

  This is a genuine Ford fuel injection supply tube assembly, catalogued under base number 9J323, fitted to the 5.0L V8 fuel system in the Mustang. The tube assembly carries pressurized fuel within the injection system as part of the high-pressure delivery path that supplies the engine's fuel injectors, ensuring a steady and properly pressurized fuel feed. Formed from precision metal tubing, it follows the factory routing and mates to its system connections with the correct geometry. Owners and technicians replace this tube when it leaks at a fitting, weeps fuel, becomes corroded, is damaged during engine work, or no longer seals dependably, since a fuel-line leak is a safety hazard and can cause hard starting, fuel smell, or driveability faults. Because it is a precision high-pressure fuel component, Ford supplies it as a complete assembly rather than a repairable line, and installation requires cleanliness and correct fitting torque. This tube carries the JR3Z-9J323-B designation, a revision within the 9J323 fuel tube family for this application. Built to Ford specifications, it matches the original routing, connection geometry, and pressure rating for a direct fit without modification. Fitment covers the 5.0L V8 Mustang across the 18-23 span. Confirm the engine, the revision, and your existing part number against the Ford catalog before ordering, and relieve fuel pressure and follow the published service procedure when installing the tube.
