14.7 FUEL FILTER
Engine running problems may have different origins, including dirty fuel. The injection pump
may wear out if there is water in the system. The water results either from the condensation
resulting from an insufficiently filled tank, or from a filler cap either not closed properly or with
a damaged seal.
In order to prevent any water infiltration, the fuel runs through two filters:
- One filter is an integral part of the engine, its role is to filter fuel very finely. Please refer to
the engine manufacturer's notes for any maintenance and for the frequency of filter changes.
- The second filter is on the pipe that links the tank to the engine, it plays the role of a water
decanter and prefilter.
Maintenance
- Purge the impurities by unscrewing the screw located at the base of the decanting
bowl(without removing it). Let the liquid run into a receptacle until the fuel runs clear. Do this
several times a year.
- Change the pre-filter at least once a year.
