Engine Fuel Filter Replacement
IMPORTANT:
Do not fill the new fuel filter with fuel before assembly.
There is a risk that contamination could get into the
system and cause malfunctions or damage.
1 Close the fuel tap(s).
2 Place a collection vessel underneath the filter drip
tray to avoid oil spillage.
Clean the filter holder.
3 Undo the coupling piece from the connector (1) if
fitted with one
4 Relieve the pressure inside the filter by opening the
drain tap (2) at the bottom of the water separator, if
fitted with one.
5 Unscrew the filter. Use a filter tool if necessary.
6 Screw off the water separator (3), from the filter.
7 Clean the sealing surfaces on the filter holder.
Make sure that the filter is clean and that the sealing
rings are undamaged.
Moisten the sealing rings with engine oil, including
the rubber seal placed inside the thread in the
center of the filter.
8 Screw on the new filter by hand until the gasket just
bottoms on the sealing surface. Then tighten a
further 1/2 turn. Install the water separator and
connect the coupling piece. Close the drain tap.
9 Open the main fuel tap.
10 Pump up fuel with the handpump (4).
11 Start the engine and check that there are no leaks.
