External fine filter
At generators with FP 320, Kubota EA 300 or Farymann
engines, the fine filter is delivered with the generator. This
fine filter should be installed in the fuel feed line next to the
generator.
5.9.2 Connection of the fuel lines at the tank
Note:
General fuel feed and return line must be connected to the
tank at separate connection points.
Connection of the return pipe to the tank
The return pipe connected to the tank must be dropped to the same depth as the suction pipe, if the generator is
mounted higher than the tank, in order to prevent fuel running back into the tank after the motor has been switched
off, which can lead to enormous problems, if the generator is switched off for a long period.
Non-return valve in the suction pipe
A non-return valve must be fitted to the suction pipe, which prevents the fuel flowing back after the generator has
been switched off, if it is not possible to use the return flow pipe as a submerge pipe placed in the tank. The instruc-
tions „Bleeding Air from the Fuel System“ must be read after initial operation or after it has stood still for a long
