Kit includes all necessary O-rings, gaskets, jets, needle, mixture screw, float bowl screws, float valve needle and seat (needle jet and other pressed-in jets are not included in kit). NBR rubber material is used on all O-rings and rubber gaskets; NBR has excellent resistance to the ethanol used in today's fuels. Applications that use paper float bowl gaskets are upgraded to High Performance Interference Gasket material. OEM jet sizes and slide needles are included in the kit.
