I installed a mechanical water temp gauge in my Cobra this afternoon and the water neck has a plug that can be removed for access to install the water temp sensor there. However when i tried to install the plug that the water temp sensor screws into that came with the gauge its too small. I had another brass plug laying around and tried it, closer but also a little to small and leaked. Does anyone know if a company makes a plug to go in there to connect the mechanical water temp sensor that would be the correct one? Or another location that would be better? :shrug: Thanks!
