I'm sure some of you geezers know this trick but I had to share it for those virgins.  Found this pic in my archieves showing the usage of a retired water bottle.  Just chop off the bottom, dry it out thoroughly and stick the neck into the valve cover grommet.  I use this on both Red and Shag.   The nice thing you don't have to clean the funnel when you get done.  Just throw the pup away.
