Inertia fuel shutoff switch
The fuel pump is located inside the fuel tank and is fixed to the top of the fuel tank by a locking ring. The fuel pump is of the regenerative turbine type and will deliver fuel at a rate of 80 liters per hour at a pressure of 3.0 bar. The fuel pump has an integral fuel tank sender unit.
The fuel tank filler pipe is constructed of plastic and is fixed to the vehicle by means of two retaining bolts. The fuel tank filler tube is fitted with a locking filler cap which seals the system.
The fuel filter is a steel canister located on the leading edge of the fuel tank. The fuel filter clamp is fixed to the fuel tank by means of two rivets and the fuel filter is retained by the clamp with a single retaining bolt.
The fuel tank is constructed of steel and has a capacity of 42 liters. The fuel tank is fixed to the vehicle by means of four retaining bolts. Fuel tank ventilation is achieved through a fuel tank rollover valve (into an evaporative emission canister). The fuel tank rollover valve prevents fuel loss from the fuel tank if the vehicle becomes inverted.
The fuel supply and return lines are made of a combination of rubber hoses, plastic and steel tubes. Plastic fuel tubes are connected to the fuel tank and fuel filter and fuel resistant rubber hoses are connected to the fuel rail. The plastic tubes and rubber hoses are joined by means of two steel tubes which run along the underside of the vehicle. All fuel line connectors are of the push connect fitting type. Supply line connections are white or are identified by a white band and return line connections are red or are identified by a red band.
An inertia fuel shutoff (IFS) switch is located behind the left-hand floor covering adjacent to the powertrain control module. The IFS switch is retained by two screws. The IFS switch is designed to cut the electrical supply to the fuel pump in the event of an accident or parking impact, thus reducing the risk of fire.
