Engine Fuel Filter Replacement
Stationary engine
1 Close the fuel valve/valves.
2 Clean the filter bracket and put a vessel under the
filter.
Remove the protective cap from the venting
nipple. Connect a transparent plastic hose to the
nipple and lower the hose into the vessel.
CAUTION!
Open the tap with caution. Hot fuel can spray out in
any direction.
3 Relieve pressure inside the filter by opening the
bleeding nipple (1).
4 Unscrew the filter, use a filter wrench if needed.
5 Clean the sealing surface on the filter bracket.
Make sure the new filter is absolutely clean and
that the sealing surfaces are undamaged.
Moisten the seals with engine oil, including the
inner rubber seal on the inside of the threaded
hole in the center of the filter.
NOTICE! Do not fill the new filter with fuel before
assembly. Contaminations may get into the system
and cause damage and malfunction.
6 Screw the new filter on by hand until the seal just
touches the mating surface. Then tighten a
further 3/4 turn.
7 Open the fuel valve/valves.
8 Open the bleeding nipple and work the pump (2)
until air-free fuel flows out. Tighten the bleeding
nipple while fuel is flowing out.
9 Remove the hose and put the protective cap back
on the nipple.
10 Start the engine and check for leakages.
