How do I get 3 water temperature sensors into a bb water pump housing? I have the stock 1/8"npt sensor, a self drilled/tapped efi water temp sensor located on the heater hose side. I can eliminate the stock sensor but i don't know if there is enough meat there to drill and tap out to 1/2npt, has anyone ever done that? any other ideas? I was thinking about using a t in the heater hose (yeas, I'd like heat in the winter) but I was concerned about the temp not being accurate, which hose is the feed off of the water pump? thanks
