The B.R.E. Small Engines Animal Breather Kit

This kit solves the problem of what to do with that empty hole into the valve cover of the Briggs Animal engines.  This kit neatly and securely helps keep dirt out of the crankcase of your engine.  It can be used as is (if your local rules allow) or it can be used in conjunction with an oil catch tank by attaching a 1/4" id fuel hose to the output of the filter element.
