I just put on a set Professional Products fuel rails and regulater, after putting everything together I had fuel leaks every where. I used Russell fittings and braided lines. But everywhere I put it together leaked, After taking them out 4 times to torque them down some more they still leaked, Anyone else had this problem. I ended up using JB weld around the fittings to just seal it off so I can get it to the dyno. I will worry about getting another set of rails and regulater another day.
