For Kohler 26 HP EFI Units:
POTENTIAL HAZARD
♦ Fuel system components are under high pressure.
WHAT CAN HAPPEN
♦ The use of improper components can result in system
failure, gasoline leakage and possible explosion.
HOW TO AVOID THE HAZARD
♦ Use only approved fuel lines and fuel filters for high
pressure systems.
Note: For Kohler 26 HP 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 26 HP EFI
Kohler Air-cooled (except 26 HP EFI)
Kawasaki Liquid-cooled
Kawasaki Air-cooled
Note: When replacing the fuel filter for the Kohler 26 HP EFI units, wet the
interior of the new filter with gasoline before installation to prevent the high
pressure pump from tearing the filter.
Fuel pressure relief and priming procedure: (26 HP Kohler EFI units only)
Service Interval: As required
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.
b) Allow the engine to cool completely.
c) Connect the black tester hose from the Kohler pressure gauge to the test
valve in the fuel rail.
d) Route the clear hose into a portable gasoline container and depress the
button on the tester relief valve.
