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 to the
“A” side.
(Position for using the internal tank.)
Remove the connecting hose of the
3way fuel valve.
Pass the hose from the external tank
through the external fuel ports and
connect to the external tank fuel inlet/return of the 3way fuel
valve.
Turn the 3way fuel valve lever to the “B” side.
(Position for using the external tank.)
Bleed air from the external tank connecting hose. Fuel can
be supplied from the external tank after completing the
above procedures.
< NOTE >
Protect the piping connecting the external fuel tank and
this generator with corrugate tubing or similar in order to
prevent interference between the generator internal parts
and the external fuel ports.
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 so that it is 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 “A” 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.
