The neck of the fuel filler pipe is positioned at the rear of the vehicle, above the rear right wheel. The fuel filler pipe and fuel filler cap are covered by a molded plastic fuel flap.
The fuel flap has the electrically locked when the vehicle is locked.
The fuel filler cap is a conventional screw-in type which is secured to the vehicle with a lanyard. The fuel filler cap must be securely installed to make sure the fuel tank venting system is sealed and potential fuel loss prevented. The fuel filler cap has a ratchet locking mechanism, it should be screwed in to a torque of 3 audible clicks. The clicks confirm the fuel filler cap is correctly tightened.
The fuel filler pipe is a stainless steel fabrication which is secured to the vehicle body with 3 brackets and nuts. A metal stub pipe, attached to the fuel filler neck, provides for the attachment of the breather.
The fuel filler pipe attaches to the fuel tank at the rear right side. The fuel filler pipe incorporates a check valve at the connection point. The in-line check valve is mounted inside the fuel filler hose, and is retained in the closed position by a spring. The check valve is only opened when the vehicle is refueled.
A breather is connected between the fuel filler neck and the fuel tank. The breather enables the fuel tank to be filled, allows for expansion of the fuel vapor and controls the fuel cut off during filling. The fuel vapor is routed to the evaporative emission canister.
