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

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.
