Fuel Flow Requirements
WARNING
If engine is equipped with a quick-discon-
nect fuel hose, you MUST disconnect the
fuel hose from the engine and the fuel tank
to prevent fuel leaks:
•
Whenever the engine is NOT being used
•
Whenever the engine is being trailered
•
Whenever the engine is in storage.
NOTE: A small amount of fuel may be
released when the fuel connector is dison-
nected.
Store portable fuel tanks in well-ventilated
areas, away from heat sources and open
flames. Close the vent screw of the fuel
tank cap, if equipped, to prevent escape of
fuel or fuel vapors which could acciden-
tally ignite. Do not allow disconnected fuel
hoses to leak fuel.
