Above is a link to a pretty good article about fuel hoses. I'm not sure how many are using rubber core fuel hose, but I have it on my car and I'm getting rid of it. I'm also switching to a return style fuel setup. There are pros and cons to that, but I think the return style is just easier over all. The big thing is that fuel dissolves rubber. Switching to Teflon is just a good idea as it is stable with modern fuel and fuel additives.
