I wish you luck with the s/s lines. The flares are very hard and so are also hard to get seated/sealed. The standard lines work the best.
Aren't you glad you didn't spend a lot of time trying to "restore" the old lines ?
Yeah, I'm very happy not to have to worry about the old lines flushing little bits of junk through the system or leaking down through a little crack somewhere. Infinitley happier to have the new lines.
I've read a lot of cautions about using the SS fitting, and since these were flaired by the manufacturer I'm fairly confident of the outcome. I bought these from The Right Stuff, but Inline Tube has some videos on their site regarding installation.
