Yeah I might go that route if this ends up not working...
I bought a prefabbed line from O'Reilly's (BH2201317A) but the thread on one of the ends of the line is incorrect even though the O'Reilly's website says it fit's a 2012 Ram 2500 4x4. Went to put it on yesterday and only 1 fitting was correct, so I figured I'd cut it off, put the old fitting on the new line and re-flare it... which didn't work out due to the el cheapo flare tool (which is being returned today)
I wouldn't mind having extra line and a good working flare tool in the shop so next time anything like this happens I can fix it and not have to make a run to the store or wait for parts to come in
I've owned several different complete hand-flaring sets - including two different Snap-On & Matco sets. My conclusion is that it seems to be an area of tooling that hasn't had much attention or innovation.
But by simply buying half a dozen kits and returning the junk ones I did find one happy exception.
There is a company that makes good flaring tools. The company is Mastercool and they use a different and far better way to make a flare. Amazon carries the entire line. This is what the pros use.
I bought the least expensive kit that uses their "Eccentric Flaring" process. Part number is PART#70058-A, and was right around $100. Heavily built, ball bearing action, and uses that eccentric wiping action to make a smooth flare. They make all sorts of kits, but that one worked for me.
The complete kit is what to get as it includes their matched tools that are all excellent quality. If you haven't used an eccentric type flaring tool before you'll need to make a couple of practice flares before you believe how easy it is to make good ones.
