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.
