IMPORTAWI': It is important to prevent
gum deposits from forming in essential fuel
system parts such as the carburetor, fuel fil-
ter, fuel hose or tank during storage. Also,
experience indicates that alcohoi blended
fuels (called gasohot or using ethanol or
methanol) can attract moisture which leads
to separation and formation of acids during
storage_ Acidic gas can damage the fuel
system of an engine while in storage,
• Drain the fuel from the fuel tank into an
approved container outdoors, away from
