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.

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 with attachment parts as in EPC.

Fuel tank (88l)

A2204707601 (top).
A2204707601 (bottom).

Fuel tank (78l)

A2204707701 (top).
A2204707701 (bottom).

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

Shown on model 220:

  • 42 - To fuel tank ventilation system
  • 80 - Fuel tank
  • 80/5 - Splash bowl
  • 80/10 - Return flow line
  • 80/11 - Fuel strainer
  • 80/13 - Riser line
  • 80/17 - Return flow nozzle
  • 90/12 - Fuel suction hose
  • 91 - Pressurization line
  • 93 - Ventilation hose
  • h - Fuel level


Shown on model 211:

  • 1 - Left suction spray pump
  • 2 - Bleed valve
  • 3 - Pressure regulator valve
  • 4 - Pressure regulator
  • 5 - Right suction spray pump
  • 6 - Splash bowl
  • 7 - Fuel pump in swirl pot
  • 80 - Fuel tank
  • A - Return flow
  • B - Feed line to engine
  • h - Fuel level

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.
