Do not use any kind of sealant on the fuel pump o ring. You may have some dirt or crud around the sealing portion of the tank. I like to blast that area with compressed air before removing the pump, then clean the sealing area with a clean rag. I then use Mercury Marine multipurpose grease to lube the sealing area and o ring. That method works very well for me.
