The fuel supply system is under low pressure from the tank 1
to the injection pump 5.
NOTE:
The representation of fuel tank is purely indicative.
Component not necessarily supplied by KOHLER.
Important
• The high pressure supply injection system is highly susceptible
to damage if the fuel is contaminated.
• It is crucial that all components of the injection circuit are
thoroughly cleaned before the components are removed.
• Thoroughly wash and clean the engine before maintenance.
• Contamination in the fuel supply injection system may
cause a reduction in effectiveness / operation of engine fault
indication.
• If the engine is cleaned with high pressure washer, then the
nozzle must be kept at a minimum distance of 200mm from
the surface, and not directed at electrical components and
connectors.
