Any recommendations for an electronic fuel gauge?

It's easy to calibrate. I have the FuelHawk shown in the link; the calibration for my 337G with extended range tanks is shown below :

0 31.8
1 37.8
2 42.7
3 46.1
4 49.4

Thank you, Ernie! Proof that there is no such thing as an old topic. I just bought a G, and this was to be the first order of business!

Of course, I will verify the numbers for my airplane but hoped to establish a minimum fuel load for takeoff referenced to the "zero" point that you have measured. That is the only thing about the extended tanks, lack of a visual check, but I'm happy to have the airplane. Too bad that Cessna never engineered a drip stick on the inboard tank. I've used them plenty of times on the airliners I've flown. Probably enough pilot vs. fuel problems to begin with. Why fly if you can't see it?

I have been looking at CiES fuel sensors and Aerospace Logic display since I got into my plane in March. Have spoken with both CiES and Aerospace Logic. Also Possibly newer Electronics International engine monitor with the CiES sensors. Been slowed down with other maintenance items. Of course always dip the tanks.

The more I look at them; I'm thinking the Insight Gem 4 Skymaster over the JPI 760. I like the display a lot better. I'm also thinking of the Strike Finder as well. I have the ForeFlight stuff on the iPad, but I love doubling up on information.

I had a WX-10 in my Piper Pacer commuter, it saved my bacon many night.

I attached the image of measurements I made with my "G" and its long-range tanks. I'm using the J-Hawk J-Air Fuelhawk 11" Universal AvGas Pre-Flight Fuel Dipstick. Also, I sincerely recommend a Fuel Stop - FuelHawk Saver attached to the fuel dipstick. It would be easy to lose the dipstick in any 337 fuel tank.

This was very time consuming work. Each reading was taken with the dipstick resting in the lateral channel that runs down the length of the wing tank. The lowest reading was made with fuel in that channel, directly below the port.

Use the chart at your own risk. Honestly, I will check the accuracy of my recorded data the next time I have the fuel below the filler ports.

The right gauge has stopped working since I bought the airplane. If the problem is in the indicator, I will install the Aerospace Logic FL212 electronic gauge on my aircraft; it is STC'd for the 337.

I'm glad you mentioned the insight Gem 4 engine monitor. I think I am going to head for that. I like the vibration analysis capability. My fuel gauge gone so I will likely be doing the aerospace logic fuel indicator with CiES probes after the holidays at the same time. (In the meantime, I still need to squeeze ADS-B out in before end of December.)

One thing about the Aerospace logic fuel gauge: per the STC it can be the only fuel gauge installed. So any later upgrade to glass engine management or glass navigation will mean the aerospace logic unit comes out (or you don’t hook up fuel to the fancy glass stuff).

I plan on replacing my capacitance system with CiES probes and then the aerospace logic indicator. The real cost will probably be the probes and wiring. But probes are compatible with a number of systems.
