I got a power disc kit from CPP and i am half way done. I got the booster on and all and i started to lign up the lines. They dont match. So i bend them to where they will. The back one is way to short and the bottom has a different size end. Do i have the wrong proportioning valve? Or am i suppost to cut and flare my own ends on? The kit came with 4 extra lines. 2 that are U shaped one of with has the same size end on both and the other has different sizes. A 3rd tha is kinda S shaped and a long one about a foot and a half. what are these for?
