Fuel System - Arctic Cat CFR 800 2010 Operator's Manual

CAUTION
Do not run the engine without the
air filter installed. Severe damage to
the turbocharger/engine will occur.

FUEL SYSTEM

! WARNING
Whenever any maintenance or
inspection is made on the fuel sys-
tem in which there may be fuel
leakage, there should be no weld-
ing, smoking, open flames, etc., in
the area.
In-Line Fuel Filter
(F 570 Model)
Arctic Cat recommends that the in-line
fuel filter be checked weekly. The in-line
fuel filter is located just in front of the
fuel pump inlet fitting. 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,
gasoline flow will be restricted; there-
fore, the filter must be replaced. To
remove and install the in-line fuel fil-
ter, use the following procedure:
1. Pinch off the fuel hose between the
gas tank and fuel filter.
2. Remove and discard the clamps;
then pry the fuel hoses off the in-
line fuel filter and remove the filter.

NOTE: The in-line fuel filter must
be replaced if obstructed. Filters
are available from an authorized
Arctic Cat Snowmobile dealer.
3. Install the new in-line fuel filter (if
necessary) in the fuel hose so the
arrow on the filter points toward
the fuel pump. Make sure the fuel
hoses fit tightly on the filter. If the
existing fuel hose does not fit
tightly on the filter, cut 6 mm (1/4
in.) from the end of the fuel hose;
then install on the filter and secure
with new clamps.
MAINTENANCE
! WARNING
The fuel hoses must fit tightly on
the fuel filter. If the fuel hose length
doesn't permit this procedure,
replace the fuel hose. Also, after
installing the fuel hoses on the fil-
ter, check to be sure that the fuel
hoses do not contact any hot or
rotating components.
In-Line Fuel Filter
(F-Series Z1/
Z1 Turbo Models)
Arctic Cat recommends that the in-line
fuel filter be replaced every 5000
miles. The in-line fuel filter is located
just inside the left-side access panel.
The filter must be clean to allow the
fuel hose to transmit the amount of gas-
oline required.
If the in-line fuel filter is obstructed,
gasoline flow will be restricted; there-
fore, the filter must be replaced. To
remove and install the in-line fuel fil-
ter, use the following procedure:
! WARNING
Since the fuel supply hose may be
under pressure,
safety glasses; then remove the
hose slowly to release the pres-
sure. Place an absorbent towel
around the connection to absorb
the fuel.

NOTE: Before removing the fuel
filter, take note of the filter inlet
and outlet for installing purposes.
