Re: No Thermostats
Pech33. The gauges are Stewart Warner. The temp has a tube running from the back of the gauge to a sensor in the left cylinder head. The vacuum gauge is tapped into the intake manifold and connected with a 1/8" plastic tube. The oil pressure gauge is fed from a port on the left rear of the engine, again with a 1/8" plastic tube. No electrics involved, unless you want to have lights in the backs of the gauge to see them at night. There are some that worry about the oil gauge being fed by a plastic tube, but I covered mine with wiring harness sheath at potential wear points. I installed these before I could get all my dash instruments working, so I could drive the car and know what the health of the engine was. The "Moto-Minder" vacuum gauge was just for fun, but also indicates the health of the engine.
