I am planning some maintenance on my next trip home, and one thing I want to solve is a leak where the brake line fitting goes into the resevoir at the firewall. The nylon fitting is leaking where it screws in. When I last looked at it, it was able to turn it in by hand another 3/4 turn and it felt "soft". Anybody have advice about replacing it, in particular with brass or another nylon fitting? Any part numbers that work better than others? I saw something about this a month or so ago, but as usual, I can't find it now. Thanks.
