FUEL SYSTEM
The fuel lift pump (C, Figure SP-3) draws fuel from
the fuel tank (K) and pushes it through the fuel fil-
ters (G) to the injection pump (A). The injection
pump forces fuel through the injectors (E), which
atomize the fuel and spray it into the combustion
chamber of each cylinder. The low pressure leak-
off return line (H) from the injection pump passes
through each injector and returns to the fuel tank.
DRAINING FUEL WATER
SEPARATOR
The water separator on the bottom of the fuel filter
(Figure SP-4) should be checked daily and drained
when needed. Frequency of draining will be deter-
mined by operating conditions and quality of the
fuel.
To drain the separator, use the following procedure.
