Spridget water temp sensor

[Dayle Frame]

Once again I throw myself at the mercy of the Spridget Intelligencia.

In an effort to 'modernize' my Spridget, I'm putting in all electronic gauges. So I need a fitting to adapt the 1/8" NPT water temp sensor to the port on the head. It appears to be 5/8"-18 bolt thread. But that doesn't seem right. Another forum suggests that it's a 3/8" BSP. So what's the answer? Find a goofy adapter? Plug the port and put the sensor somewhere else?

I can't be the first guy to go down this road so there has to be an easy answer out there. Any ideas, folks? Email me at hdf3.wtr80@gmail.com with any pertinent suggestions.

Use the electric sensor for the later MGBs. However with that said, I wouldn't call updating to electric gauges progress.

Dayle,
I am using a Stack sensor in the original location. Use a stock fitting into head with an male - female aluminum adaptor which fits the stock fitting. I don't remember the size of the male but I think female for the Stack is a 1/8" npt. I had to drill it out to make room for sensor. I'm out of town but can send you a picture when I get home.

I'd tap the head out to 3/8 pipe, very easy to do, then use a bushing.

+1. This is what I do. I bought a tap that size just for that purpose.
