Fuel tank
W220 has fuel tank (A2204707601) with 88 liter (23 galon) volume, unless vehicle has option code 282 (SKI-BAG) or 308 (REFRIGERATOR IN REAR) in which case the fuel tank (A2204707701) has value of 78 liters (20 galons).
Fuel tank (88l)
Fuel tank (78l)
Fuel reserve
The 88 liter tank uses 11 liters as a reserve. The 78 liter tank uses 10 liters as a reserve.
The reserve is what is left when the needle is pointed all the way down to the bottom of the yellow area and the fuel warning light comes on. Hence, the fuel gauge in the instrument cluster shows the fuel level minus the reserve volume.
Splash bowl
The swirl pot is mounted in the fuel tank. The task of the splash bowl is supplying the engine with fuel in the event of a low fuel level in the fuel tank and during lengthy cornering.
The fuel return flow stream flows out of the return flow nozzle (80/17) into the splash bolw at a high velocity when the fuel pump is operated. As a result, the fuel around the return flow nozzle (80/17) is also entrained and carried into the splash bowl.

The fuel tank pressure sensor is built into the hausing of the fuel gauge.
The task for the fuel tank pressure sensor is detecting the internal pressure of the fuel tank for the leak test of the fuel system.
The output signal depends on the pressure inside the tank and is transmitted to the engine control unit.
