It is important to prevent gum deposits from forming in
essential fuel system parts such as the carburetor, fuel lter,
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.
