These easy to use fuel gauges are pre-calibrated to ensure that you always know how much useable fuel you have on board. To use simply insert the gauge into each tank until it touches the bottom. Place your finger securely over the top opening and remove to read fuel quantity from the gauge.
Nice
Purchased this for the 172SP. It is very simple to use and quite accurate. I did a few tests against the fuel truck's reading and it was spot on. Great product.

Does the job. An improvement which we institute is to clamp a PE disk to prevent dropping the fuel stick into the tank.
