Except code 494 USA version

Location
The saddle-shaped fuel tank with a fill quantity of around 66 liters is located on the underbody in front of the rear axle.
Design
The fuel tank consists of a two-layered, very stiff plastic (HDPE - high density polyethylene). Due to the "U"- shaped cut-out, the fuel tank is divided into two interconnected chambers.
Aeration and ventilation of the fuel tank (operational ventilation) takes place via the breather valves and the activated charcoal filter. Aeration of the fuel tank during refueling takes place via the refueling, limiting and bleed valve. The refueling limiting valve also prevents overfilling by closing the vent line.
Rollover valves are integrated above in the breather valves which close off the aeration and ventilation system for a rollover in order to prevent fuel escaping.
The fuel pump is built into the fuel feed module.
Each fuel tank chamber contains a fuel level indicator sensor for detection of the fuel level.
Emptying
The fuel tank has no outlet valves. Emptying is done by the tanking service or by using a suitable extractor system.
Tanking service
The fuel tank can be emptied via the fuel pump control unit (N118) without the engine running. The tanking service must be called up for this using the DAS and the following parameters entered:
Parameter 01 for "fuel pump ON"
Time "0-99999" seconds
Duty cycle of the PWM signal (pulse width modulated signal) up to 100%
During emptying the DAS must be connected and the ignition must remain switched on.
Function
The fuel supply is controlled and monitored by the ME-SFI [ME] control unit (N3/10) and the fuel pump control unit (N118). The fuel delivery performance is regulated variably from 0 to 130 l/h for a fuel pressure of 3.8 bar according to fuel requirements.
