13. Fuel Filter
The fuel filter is installed between the fuel tank and fuel
injection pump, and removes dirt/foreign matter and water
from the fuel from the fuel tank.
Fuel from the tank enters filter housing inlet and fills the
sediment bowl. The fuel is filtered as it passes through the
filter element, leaves the housing at outlet, and flows to the
fuel injection pump. Sediment and water settle to the bottom of
the sediment bowl.
