Has anyone had to replace the hardlines?
I have one of the three lines with a damaged nut, probably because, before I got the car, it was over-tightened to try to stop it from leaking. I thought I would just make up new hardlines myself, but they are SAE bubble flares, not metric. My ISO bubble flare tool is all metric. A quick look around the internet shows bubble flare tool kits for sale in metric sizes only; couldn't find one with 1/4" SAE dies or anvils. I have the 7/16" British Gurling nuts, but my metric bubble flare tool with the 6mm die will not work reliably on the 1/4" tubing - 1/4" being 6.3mm. (I think I have probably tried 20 or 30 times to make the flares using different combinations of SAE and metric dies and anvils to no avail. There are a bunch of discarded tube ends with distorted flares all over my workbench.)
I have tried using an SAE double flare tool to make the bubble flare, as suggested in numerous youtube videos, but they don't look like they will seal and I have heard this method is unreliable. I can probably clean up the damaged nut on the original and reuse it, but I'm not sure how reliable it will be, given that the PO looks like they had trouble getting it to seal in the first place.
Have I misunderstood something about these old style bubble flare ends? Any ideas or suggestions how to fix this? Or is there a non-metric bubble flare tool that I have not been able to find?
