Temp Gauge w/ 6 Pak Manifold

There is a fitting available at auto parts houses that you splice into a heater hose that is made just for this. I have one I'm going to use for the temp. sensor on my AMC daily driver when I convert it to MPI. I would imagine that a similar item would be available from several sources. I think I got mine at NAPA. 4 Seasons Part Number 84540. It has a hole that's tapped with 3/8" pipe threads. I'm sure a person could cobble something together with brass fittings if they tried.
