    I received many suggestions on how to connect my Magnahelic vacuum line to a double hose mouthpiece so I can check cracking effort as I rebuild/tune my regs.

    Hated to destroy a good mouthpiece but I found this old original USD one in my bin-o-parts that is as stiff as a board and would not be comfortable to use on a reg so I decided to sacrifice it to the cause.

    I'm sure I'm not the first person to do it this way but thought I'd share. When in use I would have a wagonwheel and valve in the exhaust side of the mouthpiece.

    First, took a Dremmel to the insignia to flatten the area:

    After a little hand sanding I had a nice flat surface:

    I drilled a hole and screwed in an air nipple resulting in a vacuum line to my Magnahelic. The nipple is nice and tight so I don't anticipate any leaks. Guess I could put some neoprene cement or superglue around the base but don't think it is necessary.

    The whole project took about 10 minutes so now I gotta find something else to do. Mark

    I probably would have pulled the hose off the regulator and made a T-piece there. A little hose, the T, take it off when I was done. But it looks like you already got the job done.
