You guys always amaze me. Just when I was doing brake work I come accross this. I was leaking so I found a Napa Auto Parts store. He had them but they were thinner. I had already heated the old ones and ran them accross a piece of sandpaper to flatten them. It was tough to get the one fitting to stop leaking. After repeated tries and tightening with a breaker bar it finally stopped leaking. Why is it so hard to seal those buggers?
