I've only checked out the autometer ones on autospeed so far.
AU3542-M: Sport Comp Metric Oil Temperature 40°-120°C - 2 5/8" Electric 180.90 1 $180.90
AU3531-M: Sport Comp Metric Water Temperature 40°-120°C - 2 5/8" Electric 174.45 1 $174.45
AU3522-J: Sport Comp Metric Oil Pressure 0-7 Kg/Cm^2 - 2 5/8" Electric 209.06 1 $209.06
Can I use the original sensors? Including the oil pressure?
