A Series Diesel Engine Fuel System 71
Fuel Water Separator/Filter Unit
Caution : Be sure to use the correct element.
Filtration and separation of water from the fuel is
important for trouble-free operation and long life of the
fuel system. Some of the clearances between the
pump parts are very close. For this reason the parts
can easily be damaged by rust formation and
contaminants.
The element has a valve which can be opened
regularly to drain the collected water.
Regular maintenance, including draining moisture
from the fuel water separator/filter and supply tanks, is
essential to keep water out of the fuel.
