: :Since the JDM oil pressure sending unit is pretty much unreachable, I am going to do the next best thing: Install an aftermarket gauge! :Because the JDM sending unit is on the other side of the block, apparently the stock North American location is avaialbe, with just a bolt blocknig it off. So I am thinking I will tee into there - What's the size/pitch of that hole? :Thanks!
Let me know how that works out I need to do the same thing.
