How much HP can the stock fuel lines support?

My pump has been upgraded, but I'm concerned about the fuel lines them selves. Can the stock lines support 500+HP? When do they become an issue?

Thanks

There is a very good piping/regulator analysis here (I know the author and his numbers were double-checked!):
