Nuke Performance Flexible Fuel Sensor Adapter

Nuke Performance Full-Flow Flex Fuel Sensor Adapter. Its bypass design allows for an ethanol content sensor to be used without flow loss.

With the Nuke Performance Full-Flow Flex Fuel Sensor Adapter, you can install your ethanol content sensor on both the pressure and return fuel line of your system. Sensor is not included.

Compatible with most GM Flex Fuel Sensors.

Bypass design exceeds AN-10 fuel line capacity.

AN-10 ORB inlet/outlet for maximum fuel flow.

Works on both pressure and return line.

Lightweight design with integrated bracket.

4 x Viton O-rings for maximum durability.

When using alcohol fuels, such as E85, an ethanol content sensor is used to measure the fuel at all times to maintain ECU accuracy and performance. The most common sensors have a very small flow capacity, not allowing for a high-performing fuel system. With this sensor adapter, you can install the sensor on both the pressure and return side with virtually no flow loss, thanks to its bypass design which exceeds the capacity of a Dash 10 fuel line.

Compatible with the most common OEM ethanol content sensors for your aftermarket fuel system.

Designed to work with the most common flex fuel sensors on the market from the OEM manufacturer GM (Continental), this adapter is compatible with sensors 13577379, 13577429, SE1003, 13577394, and other sensors of the same design. Many standalone ECU manufacturers such as Haltec, Cobb Tuning, Fuel Tech USA, ECU Master, AEM, Link, and MaxxECU sell sensors under their own brand. However, these components often have the same specifications as the OEM parts and work with the Nuke Performance Sensor Adapter as long as they use 9.49" (5/16") connections.

Engineered with a bypass system exceeding the capacity of an AN10 fuel line, the oversized components offer safety margins where needed.

The oversized internal bypass fuel line integrated into the Nuke Performance Full-Flow Flex Fuel Sensor Adapter exceeds the capacity of an AN-10 fuel line. The oversized internal design provides safety margins where needed and allows for mounting the sensor on both the pressure and return side of the fuel system.

Which flex fuel sensor can be used with the Nuke Performance Bypass Ethanol Content Sensor Adapter?

The Nuke Performance Split Flow Sensor Adapter has been developed to be used with all commonly used flex fuel content sensors such as Continental (GM) 13577429, 2022400116, 13577379, SE1003, and even the 13577394, which requires a width modification of 95 mm (3.75").
