Total Racing Products Rotatable Flex Fuel Fittings

The Total Racing Products Rotatable Flex Fuel Fittings offer a clean, OEM-quality way to integrate an ethanol content sensor into your vehicle’s fuel system without cutting, splicing, or replacing the factory lines. Specifically designed for cars equipped with 5/16″ (7.89 mm) quick-connect fuel lines, these fittings make adding a flex-fuel sensor simple, secure, and professional.

Each fitting locks into the existing fuel line and features a fully rotatable design, allowing the ethanol sensor to be clocked in any direction for ideal clearance and routing. Built from billet aluminum with ethanol-safe seals and a corrosion-resistant finish, they provide a leak-free connection that stands up to high fuel pressure and all ethanol blends.

Whether you’re upgrading to a flex-fuel setup or adding ethanol content monitoring to your existing build, these fittings deliver the quality, precision, and durability you expect from Total Racing Products.

The TRP Rotatable Flex Fuel Fittings are built for installers and tuners who care about doing the job right. Instead of cutting factory lines or relying on questionable adapters, these fittings connect directly between the OEM quick-connect fittings and your ethanol content sensor, maintaining a secure, high-flow connection that looks and performs like it came from the factory.

Both fittings can rotate independently once installed, allowing you to orient the sensor exactly where you want it for easy wiring and optimal clearance. The internal bore is designed to maintain maximum flow, ensuring accurate sensor readings and consistent fuel delivery even in high-horsepower or ethanol-heavy applications.
