Note: Federal EPA regulations require all model year 2012 and later
gasoline powered engines produced for sale in the United
States to be equipped with a special low permeation fuel
supply hose between the carburetor and fuel tank. When
servicing model year 2012 and later equipment, only fuel
supply hoses certified by EPA can be used to replace the
original equipment supply hose. Fines up to $37,500 may be
enforced for using an un-certified replacement part.
