    Are they just rubber fuel line with a protective sleeve? I have the one with the plug in it that leaks, Figured I would just replace all of the lines. Where do you get it, and what's it called? Thanks

    I see a lot of people reference Kennedy diesel for his fuel return kit, I think it does away with those little clips.

    It's not plain rubber. Apparently it's some sort of neoprene and GM is awfully proud of it. If you can find it somewhere else it'll likely be a lot cheaper.

    diesel injection service. I cant remember the exact web site, but do a google search on it and it will come up. They had the whole kit for pretty cheap, i think it was arround $11, and that included the copper washers for the injectors

    Found it. It is fuel line commonly used on older VW's Diesel applications, obtainable at your local import auto supply. It is NBR (Nitrile Butyl Rubber) with an outer cloth sheath. It will hold up to diesel fuel, as will Neoprene, with similar characteristics. NOTE of warning- Will NOT hold up to Biodiesel. FYI

    P.S. Google it and you'll see where I got this info.

    I'm kinda suprised there isn't more of this kind of stuff here on CK5. There's lots of cool stuff about a gasser, all over the board. Very little Diesel info /forums/images/graemlins/frown.gif

    I'm confused from reading the above. Will the factory return lines hold up to biodiesel?

    Living in Germany, I'm practically depended on the VW (& other german) products.
    I discovered that the lines are diesel resistant, but because of their metric size are just a little bit smaller in diameter than the original ones. So the extra stress let fail these lines about every 2 years.
    Therefore I kept an extra meter of the lines as a spare with me.
    No big deal, just FYI. :cool1:
