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 rear seat floorpan, forward of the rear suspension. The fuel tank has a useable capacity of 63 liters (13.9 gallons).
The fuel tank is a saddle tank design which is secured to the vehicle floorpan with two straps which are bolted in position. The fuel filler neck is produced 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 two 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 passive fuel level sensor.
An internal breather hose is 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. This enables the fuel tank to be filled and controls the fuel cut off during filling.
Fuel level inside the tank is monitored by two level sensors.
Roll Over Valve (ROV)
ROV allows vapor to escape to prevent tank pressurization in normal vehicle operating modes; however this valve is designed to close to prevent fuel leakage through the vent in the event of a vehicle roll over. An internal breather hose connects the ROV to a fuel vapor pipe connection on the fuel pump module flange. 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 (FLVV)
The FLVV allows the fuel tank to be filled to its maximum, 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. For additional information, Refer to: EVAPORATIVE EMISSIONS
