My oil return line on my car has a bad leak in it, i've called Greddy about it and all they can tell me is that it is -3 earl line. The line on my car is a stainless stell braided line. I'm just trying to figure out if anyone that either owns or has owned this kit could answer a couple of questions. First, did the kit come with this braided line? Second, if the kit did come with the braided lines what size fittings does it use? I'm also taking of the exhaust manifold to have a crack rewelded and also to have it braced so if anyone can help it would be greatly appreciated. BTW i have searched this but didn't really find anything about the lines. I have also searched the www for info on this kit and can't find any info on it.
