The Accuracy is Incredible
I had four CiES senders and an Aerospace Logic quantity gauge installed in my 79' Beechcraft B55 Baron. It was roughly $2200 for the parts and I'm guessing ten hours of labor.
The accuracy is incredible with new digital gauges. After burning 100 gallons of Avgas, I am within 1 gallon between fuel quantity gauge, JPI fuel totalizer value, and what gets pumped in by the fuel truck. I can now very accurately fuel for weight considerations and be confident of my remaining fuel, even as it gets down to less than 10 gallons in each tank. My original fuel gauges were useless as far as I was concerned. I went off fuel flow and time, which works well but will never tell you if you have a leak. Cross checking between two independent sources is better than one. I never want to be flying and not know exactly how much fuel I have.
Worth every dollar spent to me. It's a fairly simple install and both companies have excellent customer service and support. They both answered all my annoying questions.
If you are going to pull and repair something, just replace it with equipment that is so much better.
