Upgrade your fuel system’s capability without sacrificing ethanol content monitoring with this Flex Fuel Sensor Adapter. Designed to work with common OEM sensors (PN: 13577429, 13577379, 13577394), this adapter solves a major limitation of the factory setup—restricted fuel flow.

The OEM sensor becomes a bottleneck in higher horsepower builds, especially once fuel demand exceeds ~400 LPH. This adapter creates an alternative flow path, allowing your system to maintain proper ethanol content readings while supporting significantly higher fuel flow. The result is improved performance, reliability, and scalability for high-output applications.

Built from durable 6061-T6 aluminum with a corrosion-resistant anodized finish, this adapter is designed to handle demanding fuel system conditions. Featuring -10 ORB inlet/outlet ports, it offers flexibility to adapt to a wide range of fuel line sizes. Dual O-ring sealing ensures a secure, leak-free connection for long-term reliability.
