The fuel line and brake line that mount on the subframe go in between the engine brackets and the frame. The rear lower engine mount bracket holes also use the lower ontrol arm bolt. You can either run the bolt from the front so it's pointing to the back of the car or run it from the back to the front but then you have to have your engine mount brackets on at the same time. The main fuel line will bolt onto the sub frame in three spots. I found it easier to mount it onto the sub frame before I bolted it up.
