The mechanical Autometer Pro Comp mechanical water temp. gauge I'm looking at says it comes with a 1/2" NPT fitting for the mechanical sender. As far as I remember, all of the fittings in the Edelbrock Performer are 3/8" NPT. Is the 1/2" NPT a misprint? Anybody else installed one of these? What tap point did you use? Can the gauge be installed on the dash using the gauge cup with the 6 feet of capillary tubing instead of the 12 feet? Need some input here so I can speak intelligently about what I want to accomplish.
