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 a saddle tank design which is mounted under the rear seat floorpan, forward of the rear suspension. The fuel tank is secured with two straps which are bolted in position and a center fixing held in place with a nut. The fuel filler neck is produced from stainless steel.
The fuel tank provides the following:
- Storage of fuel. The system must contain a given quantity of fuel and must avoid leakage and limit evaporative emissions.
- Filling. The fuel tank must be filled in a secure way, without sparks.
- Provide a method for measuring the level of fuel in tank.
- Venting. The over pressure is not allowed, the fuel vapors must be managed through valves.
- Provide a method for delivering the fuel to the engine.
The fuel tank has a storage capacity of 63 liters (13.9 gallons).
The fuel tank contains a fuel pump module which collects fuel from both sides of the tank. The fuel pump makes sure that sufficient fuel is available in the swirl pot to supply the engine's fuel demands. The Low Pressure (LP) fuel pump supplies fuel to the High Pressure (HP) fuel pump which is mounted on the engine.
An internal bracket allows for the attachment of the suction pipe and the fuel level sensor B.
The internal breather is connected to a stub port passing through the fuel tank carcass. An external 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 fuel level sensors.
