Fuel System

! WARNING
Whenever any
inspection is made on the fuel sys-
tem in which there may be fuel leak-
age, there should be no welding,
smoking, open flames, etc., in the
area.
In-Line Fuel Filter (6000)
Arctic Cat recommends that the in-line
fuel filter be replaced every 5000 miles.
The filter must be clean to allow the fuel
hose to transmit the amount of gasoline
required.
If the in-line fuel filter is obstructed, gas-
oline flow will be restricted; therefore,
the filter must be replaced. To remove
and install the in-line fuel filter, use the
following procedure:
! WARNING
Since the fuel supply hose may be
under pressure, always wear safety
glasses; then remove the hose slowly
to release the pressure. Place an
absorbent towel around the connec-
tion to absorb the fuel.

NOTE: Before removing the fuel fil-
ter, take note that the filter is direc-
tional and the arrow should be
directed towards the engine.


NOTE: The fuel filter is located
above the recoil. To access the filter,
the access panels and hood need to
be removed.
1. Remove the hose clamps and discard;
then slowly remove the fuel hoses
from the fuel filter. Dispose of the
excess fuel from the filter properly.
2. Inspect the fuel hoses thoroughly for
any signs of cracking, cuts, or wear
points.
3. Place the new hose clamps on the
fuel hoses; then with the fuel pump
inlet and outlet noted, connect the
fuel hoses to the fuel filter. Secure
with the hose clamps.
CAUTION
Make sure the fuel filter is properly
seated into the holder.

NOTE: After
changing of the fuel filter and the
engine is started for the first time,
inspect the filter area for any signs
of leaks.
Gasoline Additives
Fuel de-icer can be used for all models.
On the 8000, periodic use of the injector
cleaner is recommended especially in the
last tank of gasoline before storage. Arc-
tic Cat Fuel Stabilizer (p/n 0436-907)
should also be added to the last tank of
gasoline before storage.
Fuel Pickup Valves
If ever there is a restricted fuel flow and a
pickup valve is suspected, take the snow-
mobile to an authorized Arctic Cat Snow-
mobile dealer for this service. If not under
warranty, this service is at the discretion
and expense of the snowmobile owner.
