Hello. I have a 550 Mule C5 with the 286cc engine. Wondering if anyone out there would happen to know the size and thread pitch of the threaded port on the back side of the oil filter adapter? I am wanting to install an oil pressure gauge and this is the only place I can find to install a sending unit. I would assume that the thread pitch would be metric but then again that is speculation on my part and is why I have posted this thread for some help.

Any help or pointing me in the right direction as to where I might be able to find this information would be greatly appreciated.

See attached photo of port.

Thanks
