I've given it a lot of thought, and to me a tachometer isn't terribly useful: You manually set the engine to run at 3600rpm at full throttle, and from there you either run the engine at idle, at full throttle 3600, or throttled down to whatever speed you need for the purpose. But a readout/indicator telling you the rpm's isn't terribly useful, at least to my mind.
I do have plans to install a fuel gauge, and have already bought the sender and gauge.
But in addtion I've considered installing one of these:
I'd hook up "oil pressure" to engine oil pressure, hook up "temperature" to a sensor inserted in the hydraulic reservoir, hook up "fuel" to the new sender in the fuel tank, and hook up "volts" to the battery.
Those would at least give you meaningful data that you might actually want or need to respond to.
Just my 2 cents.
