I looked awhile back and couldn't find what I needed. I found some adapter unions for the 3/16" front lines, but couldn't find any for the 1/4" rear line. I'm just going to reflare the stock lines and use regular SAE unions.
My problem is that the flaring tool that i bought through summit will not work on my lines. The 1\4 is too big and the 3\16 is too small so no flaring goes on. What could i do about that?
I'm in the middle of installing the Wilwood proportioning valve. Has anyone else run into this problem using the article in the tech section? Will standard nuts work on metric line?
never tried it but i'd think an american nut on metric line would work just fine. the seal is more in the flare, as long as you have a good flare, and the correct flare, i doubt if the nuts would matter.

As long as you have the right flare, and the size of the nut is close, you shouldn't have any problems.
The American (SAE) type of nuts and fittings are to be used with the double flared line, and the metric (ISO) nuts and fittings are for the bubble flared line. The SAE fittings won't accept the bubble flare, and vice-versa.
