the Electronic Service Manual (ESM) ENGINE> FUEL SYSTEM> CUMMINS 5.0L>
REMOVAL AND INSTALLATION to ensure the filters are being replaced correctly.
P008A LOW FUEL PRESSURE CONTROL SYSTEM and/or a no start condition may occur
if the procedure is not followed properly.

Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

15. Install the fuel filter housing (Stage 1)
onto the module and torque to:
25 N·m (2.6 kg-m, 18 ft-lb)


A socket must be used on the
hex on the bottom of the fuel
filter housing (Stage 1) to assist
in proper installation.

16. Reinstall the fuel filter housing (Stage 1) protector.
NOTE: If the stage 2 fuel filter will also be replaced, skip to the next page, otherwise,
continue to step 17.
17. Connect the left and right side batteries.
18. Reset customer settings that were lost when the battery was disconnected.

etc.

19. Prime the fuel system.
a. Turn the ignition ON for 90 seconds to prime the fuel system.
b. After 90 seconds, crank the engine for NO MORE than 30 seconds to start the
engine.
c. If the engine does not start, repeat steps a and b until engine starts.
d. Once engine does start, it may operate erratically and with increased noise for a few
minutes. This is a normal condition as air is being removed from the fuel system.
20. Operate the engine and check for leaks.

CAUTION: If step 5 is not performed,
the fuel filter cannot be installed
correctly and will likely damage the
fuel filter inner seal and can cause
DTCs to set and/or a no-start
condition.
6. Cap or wrap the air inlet ducts with
suitable material to avoid dirt or
contaminants from entering the air inlet
system or engine.

IMPORTANT:
 Do NOT install the fuel filter into the lid first. (Figure 24)


Be sure the filter element is seated in the housing by pushing downward on the
top of the element. If the fuel filter (Stage 2) is not fully seated in the housing
after installation, the engine can set a P008A, and/or experience a crank / no
start.

IMPORTANT: It is possible DTCs may be stored after fuel filter replacement due to air
introduced in the system. Make sure to run the engine until air is purged and use
CONSULT-III plus (C-III plus) to clear any stored codes.
