It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel
filter, fuel hose or tank during storage. Also, alcohol
blended fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to separation

damage the fuel system of an engine while in storage.
