Suction spray pump

For vehicles with four-wheel drive
On vehicles with four-wheel drive, the fuel tank consists of a left
and right chamber. Supplying fuel from the left half of the fuel tank
-3- to the delivery chamber of the fuel delivery unit -2- on the right
is the purpose of the socalled suction jet pump -1-.
Fault caused by faulty suction jet pump
Caution
Vehicle breakdown due to faulty suction jet pump.
In the event of a fault to the suction jet pump, the vehicle may
brake down due to a lack of fuel even if the fuel tank is up to
1/4 full.
If the suction jet pump is not working, up to 15 l fuel (up to approx.
1/4 of the capacity of the fuel tank) will remain in the left-hand area
of the fuel tank and the fuel cannot be sucked out by the suction
jet pump.
If the vehicle remains broken down due to a lack of fuel even if
the fuel tank is up to approx. 1/4 full, proceed as follows:
– Inspecting fuel pump ⇒ Vehicle diagnostic tester.
When the fuel pump is OK and the fuel is not drawn in:
– Add around 5 litres of fuel.
– Start engine.
When the engine starts:
– Replace fuel tank ⇒ page 226
