I have a four post lift and the car is in the air, I can see the entire line front to back and I see no other device other than the distribution block "thingy" :) in the picture above. Is there a chance that is actually a combination valve? Is there any way to tell? I have no problem getting a proportioning valve like you sent me in the rear line (if the stainless new lines allow for it), but I do not want to put two proportioning valves in line with each other, that may be BAD.
