Warning
Fuel system components are under high pressure.
Use of improper components can result in system
failure, gasoline leakage and possible explosion.
Ensure that an Authorized Service Dealer
replace the fuel filter and any components for
the fuel system.
Use only approved fuel lines, hose clamps and
fuel filters for high pressure systems.
Servicing the Fuel Tank
Draining The Fuel Tank
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open area.
Wipe up any gasoline that spills.
Never smoke when draining gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
Important
Removal of hose clamps requires special
pliers. Contact an Authorized Kohler Service Dealer for
ordering pliers.
1. Park the machine on a level surface, to assure fuel tank
drains completely. Then disengage the power take off
(PTO), set the parking brake, and turn the ignition key
to off. Remove the key.
2. Close fuel shut-off valve (Fig. 42).
3. Loosen the hose clamp at the low pressure fuel filter
and slide it up the fuel line away from the fuel filter
(Fig. 42).
4. Pull the fuel line off low pressure fuel filter (Fig. 42).
Open fuel shut-off valve and allow gasoline to drain
into a gas can or drain pan.
Note: Now is the best time to install a new fuel filter
because the fuel tank is empty.
5. Install the fuel line onto the fuel filter. Install hose
clamp close to the fuel filter to secure the fuel line
(Fig. 42).

dirty, remove it and clean the screen with a wire brush
and/or soak it in solvent.
