6. Install new filter element, cover seal and vent
cap seal. Install filter with spring at top and hand
tighten collar.
7. Prime the system by removing the vent cap from
the filter bowl and add fuel until level is about
even with the top of the filter element Reinstall
cap and hand tighten.
8. Start the engine and run for one minute. Slowly
open the vent cap and allow the fuel level to
drop to about one inch above the collar.
9. Hand tighten the vent cap.
8.5.7
Fuel Level Sensor (FLS)
An optional fuel level sensor (item1,
plies an input signal to the control system as to the % of
fuel remaining in the fuel tank. The control system will
activate alarm A00001 - “LOW FUEL LEVEL WARN-
ING” when the level reaches 15%, and (if configured to
do so) shuts the engine down when the level reaches
10%. The fuel tank level is displayed in Unit Data.
To Check the Fuel Level Sensor, do the following:
1. Ensure unit will not start automatically by dis-
abling any two way communication and placing
the STOP/RUN-OFF switch in the OFF position.
2. Verify that the in line fuse (FLS, item 10
) and PCM fuse (F8, item 18
are not open.
3. Verify that the wiring is correct, cable shield is
properly grounded and condition of connectors.
No damage to sensor; no damage, moisture or
corrosion in connectors.
4. Energize sensor circuit, (MM calling for engine
operation). Check power (approximately 12
VDC) from PCM-22 (9,
) through to
connector (13). Check ground from 2MM-24 (8)
through connector (12). Check signal (greater
than 0.24 VDC and less than 5VDC) at 2MM-13.
5. If checks in the preceding step are OK, remove
the fuel level sensor, focus tube & gaskets. With
the trailer level, verify that the fuel level sensor
flange is within one-half bubble of level using a
24 inch level. Adjust tank mounting as required.

NOTICE
Torque fuel level sensor mounting
screws to 15 to 18 inch/lbs (1.7 to 2.0
Nm). DO NOT over tighten, as little as 20
inch/pounds (2.3 Nm) will damage the
sensor.
6. Using new gaskets, reinstall fuel level sensor
components. The mounting holes are not sym-
metrical, there is an alignment hole in the sen-
sor, alignment holes and index dimples in the
gaskets and an alignment notch in the focus
tube flange to assist in aligning the components.
Install mounting screws and washers in all
mounting holes and bring to finger tight. Tighten
in accordance with the instructions provided in
the preceding NOTICE.
