    I've had no luck with search but I never do. Front hardline is stuck and my numerous attempts, tricks and cool tools have done nothing to get her to loosen up. I feel a high school prom joke coming on. In the event I trash the lines, what size are they? 6mm and bubble flare?

    :( I had this on my 430. Try a 50:50 mix of acetone and ATF. I'd that still fails then yes, 6mm and bubble flare. I ended up ordering new from Eurospares for £90 I think. A real bugger to replace.

    Acetone and ATF outperforms every penetrant out there and is backed up with scientific data!

    I'm screwed. There isn't anything left of the line nut. I have enough slack to attempt to cut the nut off and reflare inline. But just enough for one attempt lol.

    Umm, Brake pipe diameter on a Ferrari is not metric, they are 3/16", hence the strange conversion to 4.75mm. Yes they have a bubble flare, with 10x1.00mm fittings on the ends.
