Attention: TDR Forum Junkies 
But I would go electric next time, the mechanical guage require a huge tap hole 1/4 inch or 3/8 pipe. It doe not work in the out line. also go with the 100 to 280 degree range guage, my guage never move above the 140 mark, which is the lowest reading. except when backing up with trailer or stop at the Canadian border and idling for 30-45 minutes. then in jumps to 220 in the pan.
