    what is the proper term for this style fitting and flare on the end of the pipe? i went to autozone to find a 2ft length of this kind of pipe with these fittings. all the have is inverted flare pipes. i just need to add about 2ft to this pipe to get my fuel lines all buttoned up.

    funny enough...I think its called a "gm o-ring flare".... if you just need to extend it..i say cut that off..add nut sleeve with union fitting in between the two hardlines.

    ...i'm not really sure what the female end of that looks like though..it seems like you could just get another o ring and put a nnut and sleeve on the 2ft hardline and screw it in.. but not sure if its -AN or what ever.

    The fitting is called a "Saginaw" fitting.
    A GM "O"-ring fitting will prob. suffice as well.

    If you just need to extend the line.Cut it,double flare the ends and use a standard brass union to connect tube with the GM fitting to the double flared tube.

    ok yeah thats where one of the two braided fuel lines connect to at the frame rail

    took me a coupel minutes of studying the pic to figure it out

    ive got a pair of the braided lines off an 87 laying in the attic right now

    you could always patch in with flared stuff, using a cheap tube flaring kit

    do what ya gotta


    good luck

    You probably aren't going to find a section of this line with fittings on it. Maybe on one end, but that's probably it. I looked and looked for my project, it's simply impossible to make them without some very expensive machine (so I was told) and by the unavailability, I believe it.

    Couple of other options: go to a wrecking yard and see if any of the GM flex fuel lines off of FWD cars are long enough (IIRC they are only 12-18" though) as they are female on at least one end. They are right up on the engine, so easy to get, and easy to find.

    Other option is to check out Earls and similar companies, adapters are made for Saginaw to AN, but those were too expensive for my blood, it would have cost something like $50 to run all the GM parts but adapted to AN. If you only need two though, that would be fairly reasonable.

    yeah, i guess i should've mentioned that the vehicle i got this tubing out of was a '96 1/2 ton pickup. i just dropped the vortec into my blazer about 2 weeks ago and i just reused the fuel lines from the donor vehicle. i figured splicing in a couple feet of steel tubing would be a piece of cake, i didn't realize how uncommon of a fitting that was until i started looking for some. how do i get ahold of this Earls company that dyeager speaks of? that is probably the route i will take unless someone else has a better idea. problem is that the vortec requires about 60psi of fuel pressure, so i can't think of any rubber hose that can withstand that kind of pressure. all ideas are welcome, so someone enlighten me.

    I would do as was already said and cut that line then double flare both pieces and add in whatever length of steel brake line you need. Also anywhere in the system that has rubber line needs to be changed to fuel injection rubber line which can handle the high pressures.

    The o-ring to -AN fittings for my application are only $8.70 each. Cheap, easy and leak free.

    there is a hydraulic hose shop by my house that i am going to go check out and see if they have that saginaw fitting. they make custom hoses and serve the public so if i have good luck, i'll post up the name and website of the place for everyone else here that has interest in this matter. it blows me away how such a simple fuel line matter got so complicated.

    Yeah, if you find someone that can make lines with that connection, post up.

    In the entire Seattle area there was apparently one guy that could do it, but of course he was in the process of moving his equipment. I went to all the Hydraulic places, I figured they were just lazy when telling me no one else could do it, but they weren't. I can see why it's not very common to have the machine/tooling for, thats a pretty complex design.

    You need to order the hose in bulk and then get re-usable fittings instead of crimped fittings. By using -AN fittings it is easy to get reusable fittings for hydraulic hose.

    As the poster says, 2 ft of lines is all he needs, I guess it would be a simple matter to use two AN adapter fittings for that section?

    i went to the hydraulic hose place by my house and all they had was an adapter to convert to AN fittings, so that is what i did. everyone's input was very helpful. if it wasnt for this forum, i'd be running around with my head chopped off.
