FUEL FILTER
The engine running problems may have different origins, among which 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. To know when you
have to intervene and how frequently you have to change it, please refer to the engine's manual.
- The second filter is on the pipe that links the tank to the engine, it plays the role of a water decanter
and prefilter.
Drain by undoing the knurled screw at the base of the decantation bowl(but not removing it).
Allow to flow into a box till the fuel looks clean.
Do it several times a year.
Change the pre-filter at least once a year (access to it when you remove the bowl).
CLOSING VALVE OF THE FUEL SYSTEM
As for the procedures in case of fire, refer to Chapter 2.
DANGER
