Fuel system
What you should know about fuel.
Most of the fuel presently available in North America is oxygenated to some extent. This is commonly done
through the addition of ethanol. Most engines offered for sale on outdoor power equipment in the North American
markets are designed to tolerate no more than 10% ethanol by volume
Ethanol is hygroscopic, meaning it absorbs water. If left exposed to air, it will draw water out of the air.
Ethanol is an oxygenator, which means that it will oxidize (corrode) metal that it comes into contact with. Expo-
sure to air causes fuel to go bad quickly, leaving gum and varnish deposits.
Fuel used in MTD outdoor power equipment should be no more than 30 days old. Because it may already have
been stored at the refinery or gas station for a week or more, fuel should be purchased in small quantities and stored
in safety approved gas cans with the caps closed.
For storage, all fuel should be run out of the tank and engine. Anti-oxidation additives will help keep the fuel
fresher.
Servicing the fuel system
Inspect the fuel system every time the engine is operated. If dirty fuel is found in the fuel tank or fuel that does not
smell “right”, drain the fuel tank and replace the fuel filter. Dispose of bad fuel in a safe and legal manner.
Refer to the units service manual for the procedures to drain the fuel tank.
Fuel filter
1. The fuel filter is installed in the fuel tank where the
fuel line connects. See Figure 1.10.

Gasoline and its vapors are extremely flammable. Use common sense when working around
the fuel system. Avoid sparks, open flames or heat sources that can ignite the fuel vapors.
