I've got an autometer oil pressure and water temp gauges that I need to hook up before I start up my new motor. The oil pressure gauge has a 1/8" NPT Sender and includes 1/4'' NPT adapter/fittings. What size is the stock oil pressure hole in the block?
Same thing with the water temp gauge. It has a 1/8" NPT Sender and includes 3/8" and 1/2" NPT adapter/fittings. Where is the best place to tap into for water temp?
Any help would be great!
