My Tach is in need of overhaul and I have heard there is an approved electronic tach available for the 108. Does anyone know who makes it and where to source one?

Second question, does anyone know where to source a rebuild kit with the seals for the fuel primer?

Thanks in advance!

Aerospace Logic sells a digital tach, easy to install, comes with the STC. It’s a small round instrument. It is a 2.25inch instrument.
 
UMA Instruments makes several electronic/analog display instruments. I installed both a tachometer and oil temperature gauge made by them in my 108-2/Franklin. The only downside for the tachometer is it reads clockwise rather than counterclockwise, but that is actually easy to get used to. At the time I purchased mine, I enquired about a CCW movement, and they indicated by reversing the circuit board they could probably make one, but I needed the replacement much sooner than they could commit to such a design change.
