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
and formation of acids during storage. Acidic gas can
damage the fuel system of an engine while in storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. Follow the
instructions in the engine's Operating &
Maintenance Manual.
