OK. I have everything I need to do my brake system front to rear. My question is how the heck do you replace the line that goes from the valve along the frame to the rear rubber line ? It looks like the only way to get it in there is to have the body off the frame. Am I missing something simple ?? The way it turns by the last crossmember looks like its impossible to just snake it up there. I wanted to take the factory fuel line out and clean it up but that looks just as hard. Has anybody out there done this already ? The other thing that Im not sure about is the guy that built the car left the vent line for the tank in place an stuck what looks like a PCV valve on the end. Is there a better fix than that ?? Thanks !
