Fuel Filter - Jeanneau Sun Odyssey 40 User Manual

FUEL FILTER

Engine running problems may have several causes, amongst which dirty fuel is a major
one, and the injection pump will be soon destroyed by water in the fuel.
Water results either from the condensation in an insufficiently filled tank, or seeps in
through the mislocked filler plug or through a damaged seal.
The fuel is run via two filters to control the foregoing risks:
- One filter is integral with the engine to ensure fine fuel filtration (refer to the
engine brochure to find out the filter renewal frequency and maintenance work),
- The other one is a first-stage filter located in the pipe system between the engine
and the fuel tank.
Undo (but do not remove) the knurled screw at the base of the settling bowl, allow to flow
into a tray until clean, water free fuel appears. Purge the system several times a year.
Remove the bowl for access to the first-stage filter, which should be replaced at least once
a year.
