Diesel fuel filter

Drain diesel fuel filter of residual
water at every engine oil change.
Place a container underneath the
filter housing. Loosen the knurled
screws on the filter cover and on the
lower part of the filter by approx. one
turn, to drain off the water.
The filter is drained as soon as diesel
fuel emerges from the knurled screw
at the bottom. Retighten the two
screws.
Check diesel fuel filter at shorter
intervals if the vehicle is subjected to
extreme operating conditions.

Diesel fuel system bleeding

If the fuel tank has been run dry, it will
be necessary to air vent or bleed the
diesel fuel system.
Fill the tank with fuel and proceed as
follows:
1. Place a suitable container
underneath the fuel filter vent
screw to collect fuel.
2. Loosen the vent screw (arrowed)
by one turn.
3. Manually operate the in-line
supply pump slowly and steadily
until fuel discharging from the
loosened vent screw is free of air
bubbles.
4. Retighten the vent screw.
If the engine cannot be started after
several attempts to bleed the diesel
fuel system, seek the assistance of a
workshop.
