I just finished this install, only took 2 weeks , lol. Let me be very clear about what I have not seen anyone else run into or comment on. This gauge is so precise that you better make sure your sending units are in up to spec. Older planes (like my 65 PA28) may need to have new or rebuilt sending units. I sent 2, 10 hour days trying to get this gauge to calibrate- Gave up, sent Sending units to Keystone for rebuild. Once that was all together, it took 24 min per tank and that was by myself. I suggest at least 2 people though! I cant wait for my first CC to really test them out, but this gauge seems rock solid!

Easy to install, nice display, really like that it works with old float type sender units.

Have not installed yet because I am waiting for the fuel tank sending units.

Unit is super accurate. Replaced the legacy fuel tank levels in a Cessna 150 with this unit. We ended up replacing the fuel senders as well since they were original and pretty much shot. None the less the unit is very accurate. Works great with a fuel flow meter.

Excellent units my 3rd one Im installing into my Pacers. Very accurate even if your senders are marginally accurate. No hardware issues after 5 years. Its expensive but I highly recommend this.

We installed this in our Commander 112 two years ago and it is a major upgrade to the accuracy of the fuel situation. Unfortunately the price has almost doubled in two years for the FL202 so I am not sure why as we would not have purchased at this price however it is a great piece of instrumentation !

After running a tank out of fuel with a fuel gauge indicating a little less than 1/4 tank of fuel left, I purchased the Aerospace Logic digital dual fuel gauge. It takes time to properly calibrate, but when I got it properly calibrated, it is right on accurate. If the gauge indicates that I have used 17.3 gallons, then it takes 17.3 gallons to fill my tank back up. I consider that my flying is much safer now.

Cessna 182Q with Cies Senders. Seems to be an excellent product, calibration was extremely tedious but well rewarded, and the install instructions were marginal. Dont expect to reach them by phone, youll have to use email. To be sure of not wasting precious time with fuel draining and filling, aerospace logic could give more specific and thorough install instructions. In hindsight, install was simple, but only after I had to ask specific questions. After all the work though, so happy to have an accurate fuel gage. Also, pair these with CIES senders, waste of money not to pair this nice gage with quality senders.

Setup and install was straight forward if you do some good planning and prep. I installed new fuel sending units from McFarlane as part of this install. A few things I noticed. I noticed the display can be challenging to read in certain conditions with polarized sunglasses so consider your dash placement. I carefully performed the aircraft leveling and waited at least one minute after adding fuel to settle down during cal. In flight I noticed the gauge indication readings change drastically during taxi, turbulence’, pitch changes or if a turn is not perfectly coordinated guessing since the fuel tank doesn’t use baffles so fuel can slosh around. Overall in my Cessna 172 it’s a slight improvement over the old gauges I had but not the radical improvement I expected. A functioning analog gauge is just as good. Problem is these old analog gauges are getting hard to support and becoming unreliable. Seemed pretty expensive for what I gained. Wish I had just spent the money on an Fl450 instead. Indication looks pretty nice on the dash though.

Unit is well built but very sensitive if using resistor type fuel senders. I have two of these units and ran into an issue getting the second one to work correctly. After many frustrating days of work I finally succeeded by running a ground wire from sender all the way back to same ground as the instrument. I was extremely disappointed in the customer service from the manufacturer. They left me high and dry. Stopped responding to emails and phone calls. I would have had a different opinion if they would have stuck with me through the issue.
