Replacement PCV valve for Pinellas Power Products extended run time fuel kits. These PCV valves will work correctly when used as a replacement part for one of our fuel kits, due to the fact that our kits are developed to work correctly when installed according to our instructions and with the parts that we supplied. We make no guarantee that any of these PCV valves will work correctly when used on anything other than as a replacement PCV valve on one of our fuel kits. There are several different specifications of PCV valves available. Be sure to order the correct PCV valve for your generator. Before ordering this item, please be aware that I have not had any PCV valve failures. The only reason that I am making this product available is because some customers feel that they need to keep replacement parts on hand. I do not recommend doing this because it would be spending your hard earned money on something you are unlikely to ever need. If you are the type of person who wants to keep replacement parts on hand I recommend: Spark plugs, Air filter, Oil filter, Fuel filter, Quick disconnect fuel fittings and A prime ball hose.
