2.5 FUEL PUMP REMOVAL AND
INSTALLATION
The pump is located underneath the air
compressor and is accessible through the engine
compartment R.H. access door.
To remove the pump, proceed as follows:
• Clean around the fuel pump and fuel lines.
Position a container to catch any fuel that
might drain from the pump or lines.
• Remove the fuel pump.
NOTE
Only unfasten the bolts marked with arrows.
FIGURE 13: FUEL PUMP REMOVAL
CAUTION
Ensure to clean around the head of the bolts.
Debris will prevent the tool from fitting properly
and cause damage to the fasteners..
• Check that the adapter and fuel pump drive
axle are not damaged.
FIGURE 14: FUEL PUMP DRIVE AXLE
• Install the fuel pump. Torque-tighten bolts to
specification.
NOTE
Use a new sealing ring. Check that the fuel
pump drive axle sits correctly in the power
steering pump.
• Using the hand primer on the fuel filter
housing, prime the fuel system.
• Start the engine and let run for 5 minutes.
Make sure that there are no leaks.
3. DAVCO FUEL PRO 382
The optional Fuel Pro 382 diesel fuel filter
system consists of a permanently mounted fuel
processor, a replaceable filter element, a filter
element cover and collar and a fluid filter base
assembly. This system is installed between the
fuel tank and the fuel pump and is designed to
be the only fuel filter in the fuel system. The filter
serves as a water separator as well as a fuel
filter (refer to figure 15).
The filter fibers used in the Davco Fuel Pro 382
element may cause the fuel level to read
artificially high when the filter is first installed.
Over the first few days, the filter fibers eventually
become fully saturated and the fuel level will
drop to normal levels. Do not be concerned
about an abnormally high fuel level when a new
Davco element is installed.
When new, the fuel level as seen through the
clear cover in the 382 filter is very low. It rises as
dirt collects on the filter from the bottom up.
Restriction remains consistently low because
fuel always flows through clean, new media.
MAINTENANCE
Replace Fuel Pro 382 filter element when the
fuel level in the see-thru filter cover reaches the
top of the filter element or after one year of
service, whichever comes first.
