What's the point of putting different size fittings from the M/C to the proportioning valves with the same size 3/16 line? Originally, the sizes of fittings ranged from 9/16, to 5/16, to 3/16 and to 1/4.
I was just curious, because my new Proportioning valve (from summit) has all 3/16 inlet/outlets and the M/C has 3/16 for the rear and 1/4 for the front. Makes it a little easier since all the line is 3/16.
The other thing is, what's the trick to stopping leaks. I have all new lines and thought I had everything pretty straight and tight, but unsure on "how tight" I need to get them.
As long as the flare is right I usually just tighten with a good line wrench until it won't turn anymore. Never had any problem with doing that. Also make sure you start by hand so it doesn't crossthread.
