5.4 BLEEDING THE FUEL SYSTEM
While bleeding the fuel system, fuel
will escape. Collect the fuel to avoid
the risk of fire.
Dirt in the fuel system can lead to
significant damage to pump units
and housing.
Note:
The fuel system has to be bled if it has been
opened; this can be done in two ways.
-
With the fuel lift pump
-
By pressurising the fuel tank
Bleeding using the fuel lift pump
1.
Loosen the union nut on the injector.
2.
Pump fuel out of the injector pipe with the
primer pump until no more air bubbles are
visible in the fuel.
3.
Tighten the union nut to the specified torque,
see "Technical data".
4.
Repeat points 1, 2 and 3 for the other
injectors.

Bleeding by pressurising the fuel tank
To prevent deformation of the fuel
tank, the delivery pressure in the fuel
tank must not exceed 0.4 bar.
1.
Remove the fuel tank cap and replace it by a
cap with an adjustable air connection.
Note:
Use a cap (without a vent) that has a
connection for a pressure reducer valve.
2.
Pressurise the tank to a maximum of 0.2 bar.
3.
Loosen the union nut on the injector.
4.
Tighten the union nut to the specified torque,
see "Technical data".
5.
Repeat points 1, 2 and 3 for the other
injectors.
