I got this idea from a retired electronics instructor friend of mine but haven't tried it yet. Get a hot tub pressure switch and using a T adaptor connect it to the tell tale line. Run power for the meter thru the normally open contacts on the micro switch. The gauge could be mounted under the cowling. Or if you have a water pressure gauge you could tap into that and mount the hour meter on the dash. These pressure switches can be bought with adjustable pressure of 1-5 PSI. Can anyone think of any reason this wouldn't work? Silvertip?
