9-6. Connecting with External Fuel Tank

CAUTION : FIRE
 Always make sure that the engine is stopped when working on piping.
 Always be sure to wipe up any spilled fuel.
 After working on the piping, check that there is no fuel leakage.
Turn the 3way fuel valve lever
1
to the "B" side.
(Position for using the internal
tank.)
Remove the plugs(R1/2") from
2
both the external fuel inlet and
the external fuel return.
Connect the hoses from an
3
external fuel tank, as shown below.
Turn the 3way fuel valve lever to the
4
"A" side.

connecting hose. Fuel can be
supplied from the external tank after
completing the above procedures.
< Note >
 If using a hose for the piping, use oil-resistant hose
with an internal diameter of 0.31 to 0.35 in (8 to 9 mm).
 Set the fuel level of the external fuel tank from 0 to 10
ft. (3 m) from the underside of this generator. The fuel
level of the external fuel tank being lower than this
generator will result in poor engine operation or
stoppage.
 Turn the 3way fuel valve lever to the "B" side in order
to prevent fuel from flowing out from the external tank
fuel inlet/return.
 Turn the lever completely as far as possible. If the lever is not completely pressed to either side, it
might not be possible to supply fuel causing the engine to stop.
 Set the supply side so that it is 0.6 to 0.8 in. (15 to 20 mm) above the underside of the tank in
order to prevent foreign material or water from being suctioned from inside the external fuel tank.
 Set the external fuel tank return side at the same height as the supply side in order to prevent
poor engine operation due to air mixed in with the fuel.
 Refer to section "9-3 Procedures during Operation" for air bleeding.
 Some air may remain in hoses or pipes immediately after connecting the external fuel tank
resulting in unstable engine speed and engine stoppage.
 Do not leave the generator unattended for unmanned operation until you have confirmed that the
engine speed is stable.
