NOTICE
If your skin comes into contact with high pressure
fuel, obtain medical assistence immediately.
NOTICE
If a fuel injector is suspected of operating outside of
normal parameters it should be removed by a quali-
fied technician. The suspect fuel injector should be
taken to an authorised agent for inspection.
Operate the engine at a fast idle speed in order to
identify the faulty fuel injector. Individually loosen and
tighten the union nut for the high pressure pipe to
each fuel injector. Do not loosen the union nut more
than half a turn. There will be little effect on the
engine speed when the union nut to the faulty fuel
injector is loosened.
Consult your authorized Perkins dealer or your
Perkins distributor for further assistance.

If air enters the fuel system, the air must be purged
from the fuel system before the engine can be
started. Air can enter the fuel system when the
following events occur:
• The fuel tank is empty or the fuel tank has been
partially drained.
• The low-pressure fuel lines are disconnected.
• A leak exists in the low-pressure fuel system.
• The fuel filter is replaced.
NOTICE
Care must be taken to ensure that fluids are con-
tained during performance of inspection, mainte-
nance, testing, adjusting and repair of the product.
Be prepared to collect the fluid with suitable contain-
ers before opening any compartment or disassem-
bling any component containing fluids.
Dispose of all fluids according to local regulations
and mandates.
There are two types of fuel filter that may be installed
on these engines. The procedure to prime the fuel
system will depend on the type of filter that is
installed on the engine and the type of connector that
is installed on the fuel injection pump. Both types of
filter and connections are shown.
Use the following procedure to prime the fuel system:
Illustration 48 g01122124
Fuel filter with element
(1) Fuel valve
(2) Vent screw
Illustration 49 g01122125
Fuel filter with canister
(3) Vent screw
1. Ensure that the fuel valve (1) for the fuel filter that
has an element is in the ON position. The fuel
valve for the fuel filter that has a canister may be
located away from the engine. Refer to the OEM
information for further details.
2. Loosen the vent screw (2) or (3).
