Since I want to run all the stock gauges, I needed a spot to install the stock water temp sensor. The top front of the water pump housing looked like the easiest spot.
The plug at the top front turned out to be a standard 1/4" NPT thread. I used a close coupled bushing to bush down to the stock 1/8" NPT sensor. I had to tap the bushing deeper so that it would clear the March bracket. but looks like it will work OK.
