The fuel pump is situated inside a plastic reservoir clamped between the
top and bottom of the tank. It is located by ribs on the bottom of the
tank and secured at the top by means of the pump cover (7). The pump is
fitted in the tank by screwing the screw ring (10) into the pump cover
from outside the tank. Any flexing of the tank is absorbed by the fuel
pump's spring element (9).


An ejector is "driven" by the flow of fuel through the delivery line via
a T-piece. The pump is an electric rotary pump. The purpose of the
ejector is to ensure that the pump is continuously supplied with fuel.
Due to the location of the pump in the reservoir, the supply of fuel to
the engine is maintained during cornering and acceleration even when
there is only a small quantity of fuel left in the tank.


The pump can be removed through a hole under the rear seat cushions.


A non-return check valve on the pressure side of the pump, fitted in the
connecting nipple on the pump cover, prevents the pressure in the fuel
line from dropping immediately after the engine has been switched off.
The non-return valve on the return side of the pump prevents fuel from
flowing "in reverse" should the car happen to overturn.
