FUEL PRESSURE LIMITING
VA LV E
DESCRIPTION
The fuel pressure limiting valve is located on the
top of the fuel rail.
OPERATION
Fuel pressure at the fuel rail is monitored by the
fuel rail pressure sensor. If fuel pressure becomes
excessive, the pressure limiting valve opens and
vents excess pressure into the fuel drain circuit.
REMOVAL
The fuel pressure limiting valve is located on the
top of the fuel rail (Fig. 18).
CAUTION: Cleanliness cannot be overemphasized
when handling or replacing diesel fuel system com-
ponents. This especially includes the fuel injectors,
high-pressure fuel lines and fuel injection pump.
Very tight tolerances are used with these parts. Dirt
contamination could cause rapid part wear and pos-
sible plugging of fuel injector nozzle tip holes. This
in turn could lead to possible engine misfire.
Always wash/clean any fuel system component
thoroughly before disassembly and then air dry.
Cap or cover any open part after disassembly.
Before assembly, examine each part for dirt, grease
or other contaminants and clean if necessary. When
installing new parts, lubricate them with clean
engine oil or clean diesel fuel only.
(1) Thoroughly clean area at pressure limiting
valve.
(2) Remove banjo bolt (Fig. 18) at banjo fitting.
(3) Remove pressure limiting valve from fuel rail.
INSTALLATION

FUEL CONTROL ACTUATOR
DESCRIPTION
The Fuel Control Actuator (FCA) is located at the
rear of the high-pressure, fuel injection pump (Fig.
13).
OPERATION
The Fuel Control Actuator (FCA) is an electroni-
cally controlled solenoid valve. The ECM controls the
amount of fuel that enters the high-pressure pump-
ing chambers by opening and closing the FCA based
on a demanded fuel pressure. When the FCA is
opened, the maximum amount of fuel is being sup-
plied to the fuel injection pump. Any fuel that does
not enter the injection pump is directed to the cas-
cade overflow valve. The cascade overflow valve reg-
ulates how much excess fuel is used for lubrication of
the pump and how much is returned to the fuel tank
through the drain manifold.
An audible click from the FCA is normal when
operating the key from the ON to the OFF position.
REMOVAL
The Fuel Control Actuator (FCA) is a non-servi-
cable part.
FUEL INJECTOR
DESCRIPTION
Six individual, solenoid actuated high-pressure fuel
injectors are used (Fig. 14). The injectors are verti-
cally mounted into a bored hole in the top of the cyl-
inder head. This bored hole is located between the
intake/exhaust valves. High-pressure connectors (Fig.
15), mounted into the side of the cylinder head, con-
nect each fuel injector to each high-pressure fuel line.
OPERATION
High-pressure fuel is supplied from the injection
pump, through a high-pressure fuel line, into a fuel
rail, through high-pressure lines, through steel con-
nectors and into the solenoid actuated fuel injector.
The ECM actuates the solenoid causing the needle
valve to rise and fuel flows through the spray holes
in the nozzle tip into the combustion chamber.
Each fuel injector is connected to the fuel rail by a
high-pressure fuel line and a steel connector. This
steel connector is positioned into the cylinder head
and sealed with an o-ring. The connector is retained
in the cylinder head by a nut (fitting) that is
