The fuel tank is manufactured using six-layer co-extruded blow-molding technology providing both high mechanical strength and complete emissions integrity. The fuel tank is mounted under the second row seat floorpan, forward of the rear suspension. The fuel tank has a useable capacity of 63 liters (16.6 (US) gallons).

The fuel tank is a saddle tank design which is secured to the vehicle floorpan with 2 straps which are bolted in position. The fuel filler neck is manufactured from stainless steel.

The fuel tank contains a fuel pump module which collects fuel from both sides of the tank. The pump supplies the engine's fuel demands while also supplying the fuel to power the 2 venturi. The rapid flow of fuel through the venturi nozzle creates a depression which draws fuel back across the saddle into the pump side of the tank and fills the fuel pump module swirl pot.

An internal bracket allows for the attachment of the left fuel pick-up and the fuel level sensor B.

An internal breather hose is connected to a stub port passing through the fuel tank casing. On non North American Specification (NAS) vehicles an external pipe and hose connect this port to the top of the filler neck. This enables the fuel tank to be filled and controls the fuel cut off during filling. On NAS only vehicles a combined fuel vapor and breather external hose connect to this port. A pipe connection splits the combined hose to independently connect pipes to the fuel filler neck and the evaporative emissions canister.

Fuel level inside the tank is monitored by 2 level sensors.

Roll Over Valve 

The fuel tank has 3 Roll Over Valves (ROVs) to allow the fuel vapor to exit and prevent pressurization of the fuel tank in normal operation. In the event of a vehicle rollover, the ROVs close to prevent the leakage of fuel from the fuel tank.

On vehicles except North American Specification (NAS), an internal breather hose connects the ROVs to a fuel vapor pipe connection on the fuel pump module flange.

On NAS only vehicles a combined ROV and Fuel Limit Vent Valve (FLVV) expels the fuel vapor and air within the fuel tank through an internal breather hose connected to a stub port passing through the fuel tank casing.

On all vehicles the fuel vapor is then routed to the evaporative emissions canister where it is stored before being purged at intervals to the engine's intake manifold.

Fuel Limit Vent Valve - All Except North American Specification and China (CN6) Vehicles 

The Fuel Limit Vent Valve (FLVV) allows the fuel tank to be filled to its maximum. This is by expelling the air within the fuel tank through an internal breather hose connected to a stub port passing through the fuel tank casing. An external pipe and hose connect this port to the top of the filler neck.

To meet On-board Refueling Vapor Recovery (ORVR) requirements, the fuel tank and associated components are designed to minimize fuel vapor loss during refueling. This is achieved by preventing fuel vapor from the fuel tank venting directly to the atmosphere. Fuel vapor is directed into the evaporative emissions canister where it is stored before being purged at intervals to the engine's intake manifold.
