Description
Optimize your fuel system for ethanol-based performance with the Nuke Performance Full Flow Flex Fuel Sensor Adapter. Engineered with an advanced bypass design, this adapter allows you to integrate a flex fuel (ethanol content) sensor into your system without restricting fuel flow, making it ideal for high-performance and motorsports applications.
Unlike traditional inline sensor installations that can limit flow capacity, this adapter ensures maximum fuel delivery efficiency, exceeding the capacity of standard AN-10 fuel lines. It can be installed on both pressure and return fuel lines, giving you full flexibility when designing your fuel system.
Constructed from lightweight, high-quality materials and equipped with four Viton O-rings, this adapter ensures long-term durability and resistance to aggressive fuels such as E85, ethanol, and methanol. The integrated mounting bracket simplifies installation while maintaining a clean and secure setup.
Key Features:
- Bypass design eliminates flow restriction for maximum fuel delivery
- Compatible with AN-10 ORB inlet and outlet fittings
- Works on both fuel pressure and return lines
- Fits most OEM GM / Continental flex fuel sensors
- Lightweight construction with integrated mounting bracket
- Includes 4 Viton O-rings for superior sealing and durability
- Ideal for E85, ethanol, methanol, and race fuel applications
Sensor Compatibility:
Designed to work with the most common OEM-style ethanol content sensors, including:
- GM / Continental 13577429
- GM / Continental 13577379
- GM / Continental 13577394 (may require slight modification)
- SE1003 and equivalent aftermarket sensors
Also compatible with rebranded sensors used by major ECU manufacturers such as Haltech, AEM, Link ECU, FuelTech, MaxxECU, and others (using standard 5/16" / 9.49mm connections).
Why Use a Bypass Adapter?
Ethanol content sensors are essential when running flex fuels like E85, but their limited internal flow capacity can restrict high-performance fuel systems. This adapter solves that problem by routing fuel through a full-flow bypass channel, allowing accurate ethanol readings without compromising fuel delivery or engine performance.
