Vans has an UMA tachometer in their store. It runs off of the tachometer drive but offers the following caution...
UMA 2 1/4" Electronic Analog Tachometer
Part Number IE UMA-19-511-112
Made by UMA. Units are complete with a sender that attaches to the mechanical drive on Lycoming engines, with a 6’ wiring harness. This may be incompatible with some vacuum pumps, or oil filter adapters.
I have a Rapco vacuum pump and things look tight but... Has anyone tried this installation?
Thanks
