The fuel tank is manufactured using six-layer co-extruded blow-molding technology providing both high mechanical strength and complete emissions integrity and is mounted under the rear seat floor pan, forward of the rear suspension. The fuel tank has a capacity of 70 liters (15.4 gallons).
The tank is a saddle tank design which is secured to the vehicle floor pan with two straps which are bolted in position. The fuel filler neck is produced from stainless steel.
The tank contains a fuel pump delivery 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 swirl pot.
The internal bracket incorporates the Liquid Vapor Separator (LVS) and also allows for the attachment of the LH fuel pick-up and the LH fuel level sensor. The LVS collects liquid fuel and returns it back to the tank via a Fuel Limit Vent Valve (FLVV).
To meet ORVR (on-board refueling vapor recovery) 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. Instead fuel vapor is directed into the EVAP (evaporative emission) canister where it is stored before being purged at intervals to the engine's intake manifold.
