The
fuel injection pump and the fuel injectors arc precisely
manufactured and they must receive clean diesel fuel, free
from water and dirt. To ensure this flow
of
clean fuel, the fuel
must pass through at least two fuel
filters, a fuel water sepa-
rator and the
engine's
spin-on fuel filter. Visually inspect,
clean, and change these
filters according to the maintenance
schedule
in this manual.
