Sheet steel fuel tank

67 Splash bowl
70/1 Return nozzle
79 Return line

A splash bowl (67) with fuel filter (66) is installed in the fuel tank. Its task is to reliably supply the engine with fuel when the fuel level in the tank is low and during long cornering.
The fuel return jet flows along the return line (79) when the fuel pump is running at a high speed out of the return nozzle (70/1) into the splash bowl. In so doing, it carries with it into the splash bowl the fuel located around the return jet.

The fuel level (h) is also retained in the splash bowl even if the fuel level in the tank drops below the height (h).

NOTE:
On vehicles with plastic fuel tank the splash bowl is integrated directly in the tank.
The function corresponds to the splash bowl in the sheet steel fuel tank.

Splash bowl with lid
As of 1989 as a phased implementation measure on all models and on model 201.034 (190E 2.3-16) as of vehicle ident end no. 117 955 a lid with an approx. 20 mm dia. hole is fitted additionally to the splash bowl (67). This ensures that fuel is reliably supplied to the injection system even if there is only a small quantity of fuel in the tank (reserve quantity) and during high lateral acceleration.

67 Splash bowl
67/1 Separating chamber
70 Return line
71 Riser line

An additional separating chamber (67/1) is created in the splash bowl (67).

The gas vapours contained in the fuel flowing back are separated from the fuel in the separating chamber (67/1) and led upward along the riser line (71). This avoids fuel splashing noises.
