Note: When replacing the fuel filter for the Kohler EFI units, wet the interior
of the new filter with gasoline before installation to prevent the high pressure
pump from tearing the filter.
Note: It is important to reinstall the fuel line hoses and secure with plastic ties
the same as they were originally installed at the factory to keep the fuel line away
from components that could cause fuel line damage.
For Kohler EFI units: Route the fuel line hoses as shown in Figure 9.

: (Kohler EFI units only)
Service Interval: As required
WARNING
POTENTIAL HAZARD
♦ Fuel system components remain under high pressure,
even when the engine is stopped.
WHAT CAN HAPPEN
♦ Failure to relieve pressure from the system can cause
gasoline to spray or spill. Spilled fuel or fuel vapors
could be ignited by hot parts.
HOW TO AVOID THE HAZARD
♦ Allow the engine to cool completely.
♦ Safely relieve the pressure from the fuel system before
attempting to service the fuel system.
A Kohler pressure gauge with an integral relief valve (Kohler Part No. 2445504)
is recommended for relieving pressure and purging air in the fuel system.
To relieve the system of pressure:
a) Stop engine, wait for all moving parts to stop, and remove key.
