- Genuine Continental GM ethanol content sensors for reliable, accurate readings
- Two variants available: GM part number 13577429 and GM part number 13577379 short
- Universal inline fit when used with appropriate fittings and fuel line adaptors
- Works with popular ethanol analyser modules to display ethanol percentage via Bluetooth, 0 to 5 V outputs or by reading the 50 to 150 Hz raw signal

Ethanol readings are influenced by the quality and composition of the fuel. Contaminated fuel can produce inaccurate results.
