4.1.24 Fuel pressure relief and priming procedure: (Kohler EFI units only)
Note: For Kohler EFI units use only high pressure clamps and SAE R7 or R9
hose available from Exmark or Kohler. Clamps require special pliers P/N 1-
643394 (Oetiker P/N 14100118 or Kohler P/N 2445505) for installation.
Replacement Filters
Kohler EFI
Kohler Air-cooled (except EFI)
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 5.
Service Interval: As required

system before attempting to service the
