    OK, so it's time to start adding brake and fuel lines. First thought is to make my own. Buy the tools, by the materials, figure it out and get started.

    But for about the same price or less, I can buy the generic lines at the FLAPS and bend them to fit. Already flared, with fittings etc. And I can get fuel and brake lines.

    So make or by the lines. what should I do?

    Long as you've got good tools, it's just as easy to flare your own, IMHO.

    I used to by the pre done lines with fittings on them and build the systems. I really hated flare fittings as the tools seemed to be junk even when I got a good one. I used a buddies Master Cool 71475 and was impressed. Since I have 2 riggs to do ASAP and the bone heads here only stock one line in any size I sprung for the tool and the 37* adaptors so I could do AN fittings. http://www.thetoolwarehouse.net/p-3494-mastercool-71475.aspx

    I just spent $20 on 25' of tube and $9 on the majority of the fittings I would need to put on the tube. I 'think' it will pay for itself in about 3 projects (2 now, 1 later - I'm good with that). It also gives me the ability to stock some fittings and not have to worry about things much.

    I did my own brake lines from scratch and I'll second using a good quality flaring tool. The best part about being able to cut your own lengths is that it gives you more routing options. I did my fuel lines with generic lines from the FLAPS and I had connections that ended up in awkward spots that were difficult to access...and still had to make cuts to certain pieces. Buy extra tubing for mistakes. When I did mine, I didn't order any extra and barely had enough. There's lines that I wish were slightly longer...

    You can make a quick diagram so you know beforehand what fittings to order.

    Taking plenty of photos before taking things apart is a very good idea. On my first build, I set enough time aside to remove and replace the lines in one day so that things were fresh in my mind. For the first time that I had done brake lines, it actually turned out quite well.

    Try not to bend the old lines when you remove them to use as a reference. I agree that you should buy extra for mistakes.

    thanks for the suggestions. I wish I had the chance to photo the lines. It's a bare frame and I've never see what CJ8 lines look like. If any of you have a pict and could post it up......

    Other than that, I was going to look on CJ8.com and reference the CJ5. Just basically figure it out...

    That's the other one I was looking at. I decided to go with the Master Cool as it has the 37* AN stuff available.

    Found this at Jegs http://www.jegs.com/i/JEGS-Performance-Products/555/63030K/10002/-1?parentProductId=756203 and for $80 thought I'd give it a try. I can't justify $250 for a tool I will use just a couple times. From what I've read, with proper prep and taking your time, the kit should work fine.

    I also ordered a Wilwood adjustable proportioning valve. Since I am going from Disc/Drum to Disc/Disc it is my understanding the stock valve will cause the back brakes to not work right.

    As of right now I plan on running a hydroboost that I'll get from Elliott on IFSJA or maybe a corvette MC. I'm starting to think the hydroboost is overkill but then again those that run it say it's the bomb. Still undecided. Still leaning to hydroboost. Can I over brake the jeep? I'd like to be able to put in in 4 low and have enough brake to stall the motor.

    I'll also bend up the fuel lines. I found some picts over on CJ8 that shows the routing of the lines. Looks like everything is on the drivers side of the frame with an AMC v8.

    I just picked up pre-bent stainless steel brake lines for my daughter's YJ. Sure, I've bent and flared my own lines at times. But, the pre-bent stuff, fits nice, it's teh right length, and it all goes together pretty darn well. Sometimes eaiser is better than less expensive, just my two cents.

    Is that steel tubing? I just bought a 25' roll of 3/16 from NAPA and looked at the label when I got it home, is says Copper/Nickel alloy. Should I use this for brake lines?

    Alright guys, I just got my new brake flare tool and it is SOOOOOO worth the money!!!! I've bought a few of the regular ones over the years and frankly they suck. They work sometimes but not usually and the times they don't work are when you don't have any extra line to spare.mehh

    Here's the one I got, Exact same thing as the Eastwood one but $46 dollars cheaper! From what I can tell the Eastwood one goes on sale sometimes, (maybe even as low as $160-$180) but it was listed at $249 (plus tax and shipping) currently and they wouldn't budge on price. Got mine form Tooltopia:

    http://www.tooltopia.com/k-tool-int...se&utm_term=KTI70081&utm_campaign=shopping_r1


    Good quality tool, It's accurate and very quick. It takes way longer to cut the tube then flare it! Tried it on 5/16" as well and just as easy, you can't do that with the regular ones. If your plumbing a whole vehicle I'd say it's way worth the money, if your worried about the cost chuck it on ebay when your done and get your money back on it!:)

    Thanks for the link. I'm going to try the new cheapie since it's new and I already have it. If it does not work, I'm gong to get one like you got. Thanks for the info. More than likely it just saved me 50 bucks.......

    If I can do it, anyone can. Just take your time and be anal about lining the tube up in line with the double-flaring tool. Make some practice flares. You'll be good at it in no time.

    Fuel lines you can do single flare, brake must be double flare.

    The key is prep, prep, prep with flaring the tube. Make sure it's deburred inside and out and make sure the cut is perfectly flat. I use a small flat file for this. I also put a slight chamfer on the outer edge of the tube to make sure all burrs are removed.
