FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS SUCH AS

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.

Rust and/or dirt in your gasoline will cause problems.
• If possible, store your unit indoors and cover it to give
protection from dust and dirt.
