The problem that I am looking at now is that I'm most likely going to have to drop the gas tank to replace the brake line, because the whole line doesn't look too great. Thanks to the wonderful road salt...
No need to drop the tank.
You can use a long line and tape over the end and thread it through , leaving the old line in place.
The tape will keep any crud from entering the end of the line as well as keeping the fitting in place.
