FUEL LINES
Check the fuel lines every 50 hours of operation.
If the clamp band is loose, apply oil to the screw
of the band, and securely tighten the band.
Parts of the fuel line are made of rubber. The fuel
lines may become worn out whether the engine
has been used much or not. Replace the rubber
fuel lines and clamp bands every two years.
If the fuel lines and clamp bands are found worn
or damaged before two years’ time, replace or
repair them at once. Bleed the fuel system after
replacement of any of the fuel lines, see TO
PRIME THE FUEL SYSTEM. When the fuel lines
are not installed, plug both ends with clean cloth
or paper to prevent dirt from entering the lines.
Dirt in the lines can cause fuel injection pump
malfunction.
There is a valve located under the fuel tank. This
valve can be used to shut off the fuel flow if the
fuel lines need to be serviced.
