4310 temp sensor thread size?

[TractorGuy]

Anybody know the thread size on the 4310 temperature sensor? I am looking into sticking a generic gauge on mine and they all come with a 1/8" NPT sensor. I want to figure out if I can find an adapter bushing.

Edit: May have found a solution. There is a plug under the sensor that is labeled M16 in the parts list that looks a little more accessible than the sensor itself. Should be able to find one of the commercially available oil pressure / temperature adapter kits with that size.

There are also 3 plugs P/N M810638, Key 8 in the drawing. No idea the thread size, if a better spot, pull one and determine thread size?

Thanks Zebrafive. I will look at those.

Trying to come up with something that doesn't look too hodgepodge. I found a nice two gauge pod that should attach on top of the cowl and not look to out of place. I need to add generic fuel and temp gauges since both are being affected by whatever is wrong in the cluster.

The other roadblock is the stock fuel sending unit is a 5-95 ohm unit that reads 95 at empty. All the generic gauges in that range are reversed and use the higher ohm reading at full. I guess having a gauge that reads backwards would be better than no gauge but it would be nice to have them both work as they should.

Those appear to be 1/2" NPT with a female allen. The one on top should work great for my use. Thanks again for pointing those out.
