Looking for M20K 231 Dual Fuel Flow / Manifold Pressure Gauge

[jgarrison]

Looking for the round dial FF/MP gauge from a 231. Any of you that have put in an EDM-900 or 930 have one they want to part with?

[Phil EF]

I have one if you’re still looking.

Somebody should let @jgarrison that he has a message or three... ^^^^

Best regards,

You very well may be able to get yours rebuilt now.  A couple of years ago I could not find a shop that had the parts or a replacement from any of the various parts vendors.  I ended up getting a digital replacement from Aerospace Logic.  No complaints about the unit, just like all digital displays it took a little getting used to. 

So if you can't find one and need to buy new, you're looking for one of their MF200K30 (vs the 60GPH version).  One MAJOR NOTE with them, they did something really strange with the STC that  you MUST use their transducer and it does NOT work with JPI (or prob. any other fuel totalizer).  So if you have a JPI (or other) my mechanic made a field mod to add a really long fuel line and put in the original JPI transducer as well as Aero Logic's.  (Really long so there was no turbulence between either transducer.)

I have the aerospace logic MP/FF gauge we removed to install our GI275 engine monitor. I believe we still have the sensors themselves. worked perfectly when removed, acts as a fuel totalizer as well. 
 

PM if you’re interested in it.

Thanks Pete.  I have mine at Instrument Overhaul Service.  They couldn't salvage the first one I sent so I sent them my spare core for parts.  We'll see how it goes and I'll keep looking.  Thanks for the recommendation, thanks.  I'm not a big of digital gauges but I may not have a choice.
