I bought a set of gauges a while back, and have been researching here to find the best place to install the sending unit for a mechanical temp gauge. It came with a 3/4" fitting that is supposed to thread into the block or intake manifold. My manifold doesn't have a 3/4" hole for the fitting that I can find. I did find a plug on the bottom side of the intake manifold that I think is 3/4" but I'm not sure and it's hard to get at. Does anyone know if that plug goes into the water jacket, or into the exhaust run? I've read about putting a fitting in the heater hose near the thermostat, but really don't want to cobble something up. If I bush the fitting down to fit in the block, I can't see where it would get enough flow into it to get an accurate reading. Any other suggestions?
I'm not sure what tomorrow will bring, but it can't be any worse than what I've already been through.
