I have to replace the lines that go from the proportioning valve back to the rear wheel wells. Does anyone who has done this happen to remember how long of a piece they needed and what the tube diameter was? I'm pretty sure that the tube diameter is 5mm but I'm pretty sure that even the longest length at the parts store will be too short to do it in one piece. If the size is 5mm, it is close enough to a 3/16" line that I can but a 20ft. roll of 3/16" stainless tubing and put metric ends on it. I have the double flare tool so flaring it won't be an issue. Has anyone gone this route before?
