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