You guys rock. It is good to come hear and pick up ideas. Thanks a bunch.

If you decide you want to inject it into the intake through a vacuum line, use a little caution. You don’t really want to stall the engine when doing it. Just add a little at a time as the engine stays running. You’ll stall it if you get too aggressive with the amount you add.

Sure will do so. I will re-watch the posted video again.
