Fuel Filter: Description and Operation
FUEL WATER SEPARATOR/FILTER UNIT
CAUTION: Be sure to use the correct filter 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 is essential to keep water out of the fuel pump.
NOTE: If excess water re-appears in the fuel water separator filter in a short period of time, the fuel tank must be removed, drained and cleaned.
