Well, the deal is that you have to have precisely the right angle or the bolt will not thread. Haha. Thats a joke. We've added a show on Friday, be sure to come by. You're not the first. I've probably spent a cumulative year trying to thread line fittings on brakes, power steering, and fuel systems. They stink. These new composite quick-release fittings on new models are a godsend. You can make it easier by not competely tightening one side first. Just get a few threads started, then try the other side. You can also look up and down the line and see if there is a clip that you can loosen to get a little flexiblity in the pipe. Otherwise, have fun. By the by, are you the dude with all the misfire and lean codes? The one that Ray hates?
