Fuel Level Sensors
The aft tank has a single float sensor, one 25" KUS Americas SSS/SSL Series Fuel/Water Tank Sensor. The sensor was replaced new on 06/02/2026.
This sensor's 2 dedicated contacts are run back to the nav desk cabinet and wired directly into an ESP32 microcontroller - a 150Ω resistor forces the line to a readable range.

The aft propane locker has a 10/11 lb (they are frustratingly sold under both names) Flame King tall tank, with a Mopeka Pro Check Universal Sensor attached. This sensor feeds to HA via BLE.
