Fuel Filtration System - Service
Engines that use bio-gas may require special
equipment for processing the fuel. Service the fuel
filtration system according to the instructions that are
provided by the OEM of the equipment.
Fuel System Fuel Filter
Differential Pressure - Check
A fuel filter differential pressure gauge may be
installed in order to determine when the fuel filter
requires service.
A fuel filter differential pressure gauge indicates the
difference in fuel pressure between the inlet side
and the outlet side of the fuel filter. The differential
pressure increases as the fuel filter becomes
plugged.
Operate the engine at the rated speed and at the
normal operating temperature. Check the fuel filter
differential pressure. Service of the fuel filter depends
on the pressure of the fuel system:
•
For the service of the fuel filter on the low pressure
gas fuel system, refer to the OEM for information.
• For the service of the fuel filter on the high pressure
gas fuel system, refer to the OEM for information.
Hoses and Clamps -
Inspect/Replace
Inspect all hoses for leaks that are caused by the
following conditions:
•
Cracking
•
Softness
•
Loose clamps
Replace hoses that are cracked or soft. Tighten any
loose clamps.

Do not bend or strike high pressure lines. Do not in-
stall bent or damaged lines, tubes or hoses. Repair
any loose or damaged fuel and oil lines, tubes and
hoses. Leaks can cause fires. Inspect all lines, tubes
and hoses carefully. Tighten all connections to the rec-
ommended torque.
Check for the following conditions:
i02478685
•
End fittings that are damaged or leaking
•
Outer covering that is chafed or cut
•
Exposed wire that is used for reinforcement
•
Outer covering that is ballooning locally
•
Flexible part of the hose that is kinked or crushed
•
Armoring that is embedded in the outer covering
A constant torque hose clamp can be used in place
of any standard hose clamp. Ensure that the constant
torque hose clamp is the same size as the standard
clamp.
Due to extreme temperature changes, the hose will
heat set. Heat setting causes hose clamps to loosen.
This can result in leaks. A constant torque hose
clamp will help to prevent loose hose clamps.
Each installation application can be different. The
differences depend on the following factors:
•
Type of hose
•
Type of fitting material
i02430593
•
Anticipated expansion and contraction of the hose
•
Anticipated expansion and contraction of the
fittings

Pressurized System: Hot coolant can cause seri-
ous burns. To open the cooling system filler cap,
stop the engine and wait until the cooling system
components are cool. Loosen the cooling system
pressure cap slowly in order to relieve the pres-
sure.
1. Stop the engine. Allow the engine to cool.
