A 1" tee has a 3/4" barbed hose fitting on each end. The leg of the tee points up, and I screwed in a 8" aluminum pipe (also from McMaster). I tapped a small block of aluminum to screw to the other end of the pipe, and mounted my radiator cap on top of that. A clear nylon tube will go to the bottom of a catch can (as soon as I can get it mounted). Not a heavy system, cheap, and saves you from having to develop aluminum welding skills. --------------090001060708090602030708 Content-Type: text/html; charset=windows-1252 Content-Transfer-Encoding: 8bit On 03/25/2011 12:52 PM, Ed Anderson wrote:

McMaster-Carr has aluminum plumbing fittings that I used to build an air capture tube. A 1" tee has a 3/4" barbed hose fitting on each end. The leg of the tee points up, and I screwed in a 8" aluminum pipe (also from McMaster).
