Nuke Performance flexible fuel sensor

Flex fuel sensor, ethanol content sensor for your flex fuel converted vehicle. Compatible with all major ECUs on the market.

The Engine Control Module uses the flex fuel sensor to adjust the air/fuel mixture and ignition timing for efficient operation. This is a genuine GM/Continental ethanol content sensor, in a smaller version and without integrated mounting points.

Nuke Performance AN-10 Full Flow Flex Fuel Sensor Adapter with oversized bypass function. Used together with the Nuke Performance Full Flow Flex Fuel Sensor Adapter, it enables the sensor to be connected to both the pressure and return line of the fuel system with minimal flow loss. The Full Flow Sensor Adapter's bypass function over-sizes the AN10 inlet and outlet, maximizing flow while still providing accurate sensor readings. For 13577429 sensors, the adapter also doubles as a bracket, allowing the sensor to be securely and effectively mounted.
Manufacturer Part No: 13577429. Dimensions: 76 x 95 x 30 mm (3.0 x 3.7 x 1.2 in). Inlet/Outlet: SAE 9.49 (3/8").
