Hmmmmm, I'm curious as to why it's 1/4", mine was 3/16" from the MC to the line lock. Did you happen to get the kit when you bought the line lock? It was an extra 20 bucks I think, that would have had what you needed I believe.
No the line locks where in there before I got the car. But whoever installed it used a bunch of compression fittings to put it all together. I'm trying to get it done with the least amount of fittings I can. I'll look up the kit and see if Incan get the extra stuff.
