Fuel Filter - Kubota EA330-E4 Series Workshop Manual

[5] FUEL FILTER

Each moving part of the injection pump and nozzle is
extremely precision machined, and clearances of their
sliding parts are extremely small. Fuel itself serves as
lubricating oil. For this reason, it is extremely important
to completely remove water and dirt contained in fuel.
This fuel filter, which uses very fine filter paper,
serves to separate and filter dirt in fuel and water
accumulated in the tank.
After passing through the filter element (6) from
outside to the center of the filter, the fuel flows to the
injection pump from the fuel outlet port (1).
When the filter element (6) is replaced, or the pipe is
removed, or air enters together with fuel, air is
automatically bled from the air vent port (2), (3).
