I found this 3/8 NPT to 1/8 NPT inverted flair. Hemichuck is this what you are talking about? Could I run my mechanical water temp guage with this setup and run the heater hose out of the bigger 3/8 NPT hole?

I dont think you mechanical sensor will go thru a 1/8 NPT threaded hole, let alone one with an adapter.

I would just drill and tap the intake, that is what I did on my LD340, it is not hard at all.
