Avoiding Fuel Flow Restrictions
NOTICE
Adding components to the fuel supply system can damage the
engine. These additions can restrict fuel flow, stall the engine
at low speeds, and create lean fuel conditions at high speeds.
Follow all regulations for fuel system installation and do not
add any additional components to the fuel system.
Fuel Requirements
Use a major brand of unleaded gasoline, preferably without
alcohol.
NOTICE
The use of improper fuel can cause serious damage to the
engine. Damage resulting from the use of improper fuel is
considered engine misuse and is not covered under the limited
warranty. Use only the recommended fuel in the engine.

passageway corrosion may occur due to the accumulation of exhausted lead
particles. Automotive fuels that contain fuel injector cleaner are recommended for
added internal cleanliness.
