1934 V8 temperature sensor
I would like to monitor the water temp in my '34 V8. I bought a gauge from Snyders that is for a Model A. I was hoping it would work as my water pumps are tapped for 1/2 NPT. Well the unit has a 1/2 fitting threaded into a 3/4 inch fitting. I thought I could take it apart and just thread the 1/2 inch part into my water pump. Nope. It leaks. What are folks using to get temperature reading on 1934 flathead V8's?

Re: 1934 V8 temperature sensor
The port in those pumps - if they are the 35-36 left - are not NPT. There is a seat at the base of the treads in the pump for the temp bulb(if that's what you have). You will need an adapter. I got my adapter from John Wolf & Co in OH.

34 water pumps do not have a threaded hole for a temperature sensor. 35 & 36 LH pumps Do have the temperature port which has a SPECIAL SEAT and the threads are 5/8-18 which is not an NPT thread.
