I am in the process of a tank,fuel pump, fuel lines project on my Suburban. I am trying to save a bit and get everything off Ebay. When I ran a search for fuel lines the first thing that came up was a guy selling a set of nylon fuel lines. All three for about a hundred bucks. Has anyone used the nylon and are they any good? Also I have heard stories of guys putting in new pumps only to have them fail in a couple of months. Is there a particular brand that is recommended over others? Thanks
