555074 Rubber Breather Grommet

Fits Clone or B&S 5hp engines.   Inserts into the valve cover. This is an easy, handy way to hook up a catch can to catch any oily spray.  Use a section of fuel line, a plastic bottle, a few zip ties, and you are in business.  Remember, your catch can should always be vented to allow crankcase gasses to escape freely.
