Nuke Performance Full Flow Flex Fuel Sensor Adapter

This Nuke Performance full flow flex fuel sensor adapter is used when running alcoholic fuels such as E85, an Ethanol content sensor is used to measure fuel at all times in order to maintain the accuracy and performance of the ECU. The most commonly used sensors have a very small flow capacity which doesn't support a high-performing fuel setup. With this sensor adapter, you can put the sensor on both the pressure and return side with close to no flow loss, thanks to its bypass design which surpasses the capability of a AN10 fuel line.

Please Note: A flex fuel sensor is not included with this adapter and is sold separately.

• Fits most common GM flex-fuel sensors.
• Bypass design exceeds AN10 fuel line capacity.
• ORB10 inlet and outlet for maximum fuel flow.
• Works on both pressure and return fuel lines.
• Lightweight design with an integrated bracket.
• Utilises 4x Viton o-rings for long-term durability.

*First measurement is without the bracket, second measurement is with the bracket.

**Sensor 13577394 needs modification before application.

Further Information

Fits all of 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 OEM manufacturer GM / Continental, this adapter works with 13577379, 13577429, SE1003, 13577394 and other sensors of the same design. Many of the standalone ECU manufacturers such as Haltec, Cobb Tuning, Fuel Tech USA, ECU Master, AEM, Link and MaxxECU, sell sensors with their own branding. However, these normally have the same specifications as the OEM parts and work with the Nuke Performance sensor adapter as long as they use SAE 9.49 (5/16") connections.

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 together with all the commonly used flex fuel content sensors such as GM / Continental 13577429, 2022400116, 13577379, SE1003 and even the 13577394, which needs to be modified to a width of 95mm (3.75").

Designed with a bypass design that exceeds an AN10 fuel line capacity and oversized components give you headroom where you need it.

The oversized internal bypass fuel line integrated within the Nuke Performance full flow flex fuel sensor adapter exceeds a AN10 fuel line capacity. The oversized internal gives you headroom where you need it and makes it possible to mount the sensor on either the pressure or return side of your fuel system.

Delivered with a lightweight bracket for an easy mounting solution for the GM / Continental 13577429 flex fuel sensor.

One of the most common Ethanol content sensors, the GM / Continental 13577429, lacks mounting points as stock. With the Nuke Performance full flow flex fuel sensor adapter, you will receive all benefits of a split-flow design while integrated brackets provide a safe and durable installation, particularly helpful alongside the often-demanding conditions within Motorsport. For the GM 13577379 and 13577394, which have their own mountings holes, you do not need to use the provided mounting bracket.
