Whats the best way to bleed the autometer setup? My car has been down for eight years and just now going back together. I believe it was Mr P body that said to fill the line with glycerin(sp?). I did this and capped the line while everything was apart. It only reads a tiny amount of pressure and another gauge under the hood reads 6psi. So I am wondering how to add fluid to this thing without introducing air into it? If I hadn't already depleated my car money getting this thing back on the road i would have put an electric one in it. Thanks for any help!
