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.
