    I need to get some new hard lines made for my brand new 1 ton 14 bolt to go from the drums to the center of the axle. Does anyone know what size fitting and what size tubing I need to get to have these things made? Any tips on fitting these things up? Thanks!

    I went down to the local parts store and bought a two lengths of brake lines that already had the fitting on the end and just bent it to where I needed it. I was about $15. Just measure out the lenght that you need.

    I think you need a different degree flange tool if you use stainless steel...

    3/16" is the size you'll need. They're the same size for 10bolts, 12bolts, 14s.....

    You can reuse yours on your truck if you want. I got mine from Inline tube. I went with the SS version. I got the double flare tool and I still couldn't flare the MOFO. So, I took it to a shop. Inline will flare em for you, but you need to the correct lenght. Maybe 16" to 20" on each side sounds about right. If you go with steel, you'll be able to flare em easy.

    Yeah, 3/16" is the correct size.

    Check out inlinetube.com.

    BTW, when flaring regular steel lines, they need to be 'double-flared.'
    The stainless steel lines need to be 'single-flared', because the metal is so much harder than the steel lines, if you tried 'double-flaring' a stainless line, you will have cracks more often than not. [​IMG]

    Anybody planning on checking out my homepage, forget it, I am still working on it!!!

    K30,

    Well, that just explains why I couldn't flare my SS line [​IMG]. I couldn't even crack the tube. I barely shaped it [​IMG] Should've known the single flare tool was the one to use....oh well, it's all good now though [​IMG].

    but its not regular 45 degree single flare, its something like a 37 degree single flare, you need a special stainless flare tool.

    Oh yeah, RaisedK5 is correct here!!! A different degree flare for the stainless too, cant use the same for the steel regular lines as the stainless!! Good eye Raised!! [​IMG]

    wouldnt the flare have to match the fittings not the material the line is made of?
