I have a friend that has the AIr8000 system from AUTOLOC and we are having problems figuring out the diagrams that are included with the system. We've gone back to the site and printed the newest instructions but it seems that these are all for dual port bags. He has single port bags. Could this be the problem or is there a special way that the single port bags have to be done as far as plumbing in the commander. HELLLLLLPPPPP!!!!!!!
