Top Flange Assembly

WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

The top flange is located on the top RH side of the fuel tank. The flange assembly is sealed in the tank with a sealing ring. A locking ring secures the flange assembly in the tank and requires a special tool for removal.

The outer surface of the top flange has four outlets with quick-fit connections and an electrical connector. One connection is the pressure outlet to the HP fuel pump mounted on the engine. The second outlet is the fuel supply to the Fuel Fired Booster Heater (FFBH) (if fitted). The third connection is for the fuel tank breather hose and the fourth connection (on ROW vehicles only) is the evaporative emission vapor outlet to the charcoal canister.

The electrical connector is located adjacent to the fuel tank breather outlet connection and provides the electrical interface to the fuel pump and the level sensors.
