If you are only rebuilding the pump, then the kit is all you need, plus jet pump oil, plug sealant, sealant for the o-ring on the cone thread lock for the bolts. Look on OSD for the kit. It comes with all above, the sealant, oil, etc. If you msg Nick he will help you out. He has helped me get mine rebuilt, and I have purchased other parts due to his support after the sales.
