Electric/capacitance fuel gauge

I installed an EI FP5 fuel flow gauge which is approved for my M-10 and after a couple of calibrations, it has become very accurate in telling me how much fuel I have left, how much I have used, what my flow rate is (more than I thought), and how much time I have left. It also has two settable fuel alarms. I think it is approved for all Coupes and Alons also.

Spring is here and if it weren't for my 415C, ser # 508 having it's prop off for overhaul I'd be flying every day as the weather gets better here in South Dakota. She's getting plenty of use now with 3 out of 4 of my kids having their licenses within the last year and fighting for flight time when the weather is right.

I worry about fuel management though. The glass sight gauge on the left wing tank down on the floor of the cockpit is hard to see, esp in flight and I've seen lots of pics of people with electronic/capacitive gauges mounted on their panels. Is there an STC for this? If so, which gauge/kit qualifies? If not, what have other people done to solve the problem?

Thanks,
