I ported out a new pump and took out the 10mm allen plug on the side. I reassembled it with a ptfe sealant which was the wrong thing to do. I took the time to remove the pump, take out the plug, and clean everything. Now what do I put on the threads? It isn't a tapered plug so it won't tighten up. You just have to screw it in until it's fully in there. I have some ideas of sealants to try but I want to hear from everyone that has experience with it.
