Anything I need to know about putting a 1/2'' stainless elbow on my march 809 with plastic head? I'm really worried about ruining the plastic threads. I have two connections on there right now that leak slightly, and I'm worried that if i try to tighten it anymore, I'm going to damage the plastic threads on the pump. In fact, I think I have already done some damage...
If you have any experience or advice, please share. Thanks.
