I heard that in this months BoatUS web Magazine but do not have acess to the article, they have an excellent article about fuel hoses made in Malaysia and other places that state they meet the appropriate standards when they don't. Can cause serious problems as they tend to start to deteriorate immediately, especially when exposed to ethanol. They were used by both manufacturers and aftermarket, as they thought they met all requirements. The bottom line is that you should check your hoses for the country of origin as well as the specifications printed. The only ones you can be sure of as made in the USA.
