< Note >
 Use always oil-proof hose in
8-10mm inner diameter as
connecting hose.
 The fuel level in the external
fuel tank should be 0 to 3m
higher than the bottom of the

cause engine malfunction or
stoppage.
 To avoid any leak from the external fuel intake and return ports, always turn the lever for 3-

 Use extreme caution when connecting the hoses. If the lever position is set improper, the
fuel may leak from either the Built-in Fuel Tank or the External Fuel Tank.
 Set the fuel intake position 15-20mm above from the External Fuel Intake bottom line,
otherwise water or garbage in the tank may come into the fuel line.
 In order to avoid engine malfunction due to air suction, set the fuel return at the same level
as the fuel intake level in the External Tank.
