Important!
Observe relevant country safety legislation and regulations.
Ensure adequate ventilation in the place of work!
Connect exhaust extraction unit to exhaust tailpipe.
The electric fuel pump must not operate without fuel! After
completing repairs and before starting engine for first time, fill
fuel tank through fuel filler pipe with min. 5 ltr. fuel.
Do not damage non-return flap when pulling out extraction
hose.
Diesel vehicles:
Note:
Before starting the engine for the first time, if the tank has been
run dry or drawn off, fill with diesel fuel and turn on ignition for
approx. 1 minute. The fuel circuit is thus filled and vented, which
results in the engine firing more quickly.
Drawing off fuel:
Start engine and allow to run.
Note:
Electric fuel supply pump runs.
In this way, the fuel is repumped through the suction jet pump
and the tank expansion line from the left to the right side of
the fuel tank.
Fuel can be drawn off from the left and right tank halves
through the fuel filler pipe down to a small residual amount.
This residual amount is drawn off after removal of the sensors
for the fuel gauge (right/left).
