fuel system is recommended. This system consisting of a

generally adequate for distances up to 300 feet. The line
size from the table below applies to the distance from the
second regulator to the demand regulator. A positive fuel
shut-off device must be installed in the fuel line close to the
engine generator set. This may be either a lockable manual

volt DC fuel solenoid valve. This optional 12 volt DC valve is
available through your local Winco dealer.
