Combine Manifold Pressure and Fuel Flow gage for a 1979 M20K

[Beard]

Does anyone know where I can find an Aerosonic Indicator Manifold Pressure and Fuel Flow gage for a 1979 M20K. Part number 651035-0207. It is original equipment for this aircraft.

A few years ago when I was looking I could not find a replacement or anyone that had parts to do a repair.  You may have better luck, but if not, I ended up getting a digital display from Aerospace Logic http://www.aerospacelogic.com

A couple of quirks about them to know if you go with them to make things easier on your mechanic for the installation:
1) They have a Fuel Flow and Fuel Pressure version, so it looks like you may want the FM200K Fuel & Manifold Pressure, but double check with them.
2) This instrument states it has "internal and external intensity control" but my version did NOT have the external control and you want the external control.
3) The Fuel Flow sender is NOT compatible with any other Fuel Computer (JPI, etc.).  So no piggy backing another device of their sender.  My mechanic had to extend the fuel line to include both senders with no flow turbulence in the line to affect the 2nd sensor.  (You can't add one sender right on top of the other.) 

Like all digital displays, it took a little getting use to from the analog dials.  But it works and I didn't really have a choice.

The smart money move would be to invest in an approved for primary engine monitor replacing all the old failing instruments and raise resell value in the process.
