2016 NISSAN TITAN fuel filter

CAUTION
Be sure to remove any old gasket material
remaining on the sealing surface of the
engine. Failure to do so could lead to an
oil leak and engine damage.7. Fill the new filter with clean engine oil.
8. Coat the gasket on the new filter with clean engine oil.
9. Screw on the oil filter until a slight resistance is felt, then tighten an additional 3/4 turn.
10. Start the engine and check for leakage around the oil filter. Correct as required.
11. Install skid plate in reverse order of removal.
12. Turn the engine off and wait more than 10 minutes. Check the oil level. Add engine
oil if necessary.
CAUTION
Your vehicle may require more frequent
maintenance if it operates on biodiesel
blends between 6% and 10% (B6 and B10) .
To avoid damage to your vehicle, the oil,
oil filter, and fuel filter will need to be
replaced after a shorter time interval than
if your vehicle was operating on pure
petroleum-based diesel. For additional in-
formation, refer to the “Maintenance” sec-
tion in the “Titan Owner’s Manual.”
FUEL FILTER REPLACEMENT (stage
1)
NOTE:
● It is possible the “Low Fuel Pressure
Service Fuel System” message will dis-
play on the vehicle information display
after fuel filter replacement due to air
being introduced into the fuel system.

●If the “Low Fuel Pressure Service Fuel
System” message is displayed on the
vehicle information display with the
engine running, complete a full key
cycle and restart the vehicle. If the mes-
sage is still displayed or the Malfunc-
tion Indicator Light is illuminated after
a full key cycle , it is recommended that
you visit a NISSAN dealer for service.
WARNING
● The fuel system (fuel pump, high pres-
sure fuel lines, fuel rail, injectors) con-
tain very high pressure fuel. To avoid the
risk of personal injury or fire;
– Do not loosen any fittings while the engine is running.
– Wait at least 10 minutes after shut- ting down the engine before loosen-
ing any fittings in the high-pressure
fuel system to allow pressure to de-
crease to a lower level.
– Wear appropriate eye protection and protective equipment as high-
pressure fuel spray can penetrate the
skin. – Never smoke or allow sparks or
flames (such as pilot lights, electrical
switches, or welding equipment) in
the work area. Never allow diesel fuel
to spill onto a hot exhaust manifold
which can cause a fire.
● Depending on the circumstance, diesel
fuel is flammable. When inspecting or
performing service or repairs on the fuel
system, to reduce the possibility of fire
and resulting severe personal injury,
death, or property damage, never
smoke or allow sparks or flames (such
as pilot lights, electrical switches, or
welding equipment) in the work area.
● Do not vent the fuel system on a hot
engine; this can cause fuel to spill onto
a hot exhaust manifold, which can
cause a fire.
● Batteries can emit explosive gases. To
reduce the possibility of personal injury,
always ventilate the compartment be-
fore servicing the batteries. To reduce
the possibility of arcing, remove the
negative (-) battery cable first and at-
tach the negative (-) battery cable last. ●
When using a steam cleaner, wear
safety glasses or a face shield, as well
as protective clothing. Hot steam can
cause serious personal injury.
● Wear appropriate eye and face protec-
tion when using compressed air. Flying
debris and dirt can cause personal
injury.
CAUTION
Clean all around the filter area before dis-
assembly. Dirt or contaminants can dam-
age the fuel system.

INSPECTION
Inspect the fuel filter housing and module for
cracks, passage blockages, and other damage. If
damage is found, replacement is mandatory.
It is recommended that you visit a NISSAN dealer
for this service.
INSTALLATION

grease.
11. Install a new o-ring on the housing. Lubricate the o-ring with petroleum jelly or white
lithium grease. NOTE:
If you are using a new fuel filter housing
that has not had fuel in it, lubricate the lip
seal at the bottom of the fuel filter element
with petroleum jelly or white lithium grease
before placing it into the housing.
12. Install the fuel filter element into the fuel filter
housing and make sure the four tabs

DRAINING WATER
WARNING
To avoid the risk of personal injury or fire,
drain diesel fuel into an approved con-
tainer and safely dispose of in accordance
with local environmental regulations.
CAUTION
Continuing vehicle operation without
properly draining could cause serious
damage to the engine.1. Shut the engine off. 2. Place a large drain pan under the drain valve
A.
3. Turn the drain valve counterclockwise1/4
turn to open.
4. Drain the filter sump until clear fuel is visible. If draining the stage 1 fuel filter housing,
drain until fuel reduces to a trickle.
5. Turn the drain valve clockwise1/4 turn to
close.
FUEL SYSTEM PRIMING
WARNING
The fuel pump, high-pressure fuel lines,
and fuel rail contain very high-pressure
fuel. To reduce the possibility of personal
injury, never loosen any fittings while the
engine is running.
NOTE: ● It is not necessary to vent air from the
high-pressure fuel system before start-
ing the engine.
● Upon ignition on the electric lift pump
will run until the fuel system is primed
or 90 seconds, whichever comes first. Purge the air out of the fuel system after refilling a
completely empty fuel tank by the following pro-
cedure:
1. Turn the key ON for 90 seconds to prime the fuel system. After 90 seconds, crank the
engine for a maximum of 30 seconds or until
the engine starts. If the engine does not
start, repeat this step.
2. When the engine does start, it may operate erratically and with increased noise levels for
a few minutes. This is a normal condition as
air is being removed from the system.
NOTE:
It is possible for a warning or indicator light
to illuminate due to air entering the fuel
system. If this happens, it is recommended
you visit a NISSAN dealer for service.
