I'm installing an aftermarket oil pressure gauge and would like to tap into where the existing sender is on the front of the block. I would like to use both senders and I know from some previous posts on this topic some of you have used a "Y" pipe fitting. Would anyone know what size pipe threads the original sender has?? 1/2"?? I'm not sure and want to go buy the "Y" fitting and have everything together prior to pulling the original sender. Any info would be greatly appreciated. Thanks!
