Thanks for all the good advice I've received on this forum. My self bent lines turned out great! I mentioned on an earlier post that I had some flat spots in my bends. It's not like I was doing this with a pair of pliers, I have a tubing bender, it's just my tubes didn't turn out as perfect as what was on the car. I didn't use any kind of filler inside the tubes while I was bending , but through trial and error and going slowly they turned out fine. One thing I will note though. I did have a couple of little drips at my connections. I tightened them as tight as I dared and they still leaked! I've twisted off/stripped more than my share of fittings and bolts. What I discovered was that after my system had come up to temperature a few times the leaks stopped. I used Teflon tape on all my connections. I was a little patient this time!!! Usually I would've either stripped/ broken these fittings or given up and paid someone else. All's well that ends well......LOL

theres a liquid thread sealant we used it on my brothers truck no more leaks

There are several brands of thread sealers out there, but I have found that the teflon tape is as good as anything.

What you dont want is kinks. Where the line bends uncontrolled and creates a straight line across the tube. A tubing bender is a good tool to have, so is a flare set. If you buy a cheap flare set you will crack the lines and probably have leaks.

There is a proper way to do flares and a non proper way to do them, But the proper way will get you a leak free connection and anything else is just line you will have to cut off and rework.

Dont use a hacksaw to cut the lines either, get a tubbing cutter, it has a small wheel that cuts the metal leaves only a minor bur, and doesnt leave any chips/finlings inside the tube.

Some cooler lines are higher than others, some run as low as 40psi, some as high as 100 or more. Depends on the trans and what has been done inside it. It isnt a 300psi line though, but you still cant use a chunk of vacuum line to cool the trans. it wont handle it for ling if at all.
