CAUTION
DO NOT replace the engine oil filter
and fuel filters at the same time. Doing
so may lead to a "dry start" condition
where the engine starts before ade-
quate oil pressure has reached all en-
gine components, leading to extreme
engine damage. Always remove and
replace one filter at a time before mov-
ing on to the next.
1.
Follow the procedure below after
2.
Loosen the fuel tank cap to relieve
any pressure in the fuel tank.
NOTE
Depending on the vehicle’s fuel sys-
tem configuration, the fuel filter hous-
ing may not completely drain of fuel. If
this is the case, take care when instal-
ling the new filter as this may cause
fuel to spill from the filter housing.
3.
Clean the fuel filter cap and
surrounding area to ensure dirt
does not fall into the fuel module.
CAUTION
Dirt in the fuel system can lead to sig-
nificant damage to the fuel system.
Failure to comply may result in equip-
ment or property damage.
4.
If required, disconnect the wiring
harness from the water in fuel
sensor.
5.
Loosen and remove the fuel filter
carefully. Use a strap wrench
towards the top of the fuel filter to
remove the canister.
6.
Make sure the O-ring does not
stick to the fuel filter head. Remove
the O-ring, using an O-ring pick if
necessary.
NOTE
The fuel filter cartridge is a disposable
filter and must not be cleaned and
reused. Dispose of the filter as chemi-
cal waste.
Fuel Filter Installation
Follow the steps below to install a new fuel
filter:
1.
If clean fuel is available, pre-fill new
filters, both pressure-side and
suction-side with clean fuel prior to
installation using the clean side
block-off plug packed with the filter.
Add the fuel to the outer area of the
filter. Do not pour fuel directly into
the center of the filter because this
will allow unfiltered fuel to enter the
system and possibly cause
damage to fuel system
components.
2.
Lubricate the sealing O-Ring that is
supplied with the primary fuel filter
with clean lubricating oil.
3.
Install the filter on the fuel filter
head by hand to the point of first
contact for the filter and head.
CAUTION
Mechanical overtightening can distort
the threads as well as damage the fil-
ter element seal or filter can.
