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 origi-
nal equipment supply hose. Fines up to $37,500 may be enforced for using an un-certified
replacement part.
