Proflow PFEFS650-10 E85 Flex Fuel Sensor Adapter — Simplified Flex Fuel Plumbing

Running a flex fuel sensor traditionally means a tangle of Y-adapters and extra fittings — more complexity, more potential leak points, more restriction. The Proflow PFEFS650-10 eliminates all of that with a single, compact billet aluminium adapter that splits fuel flow into a bypass valve parallel to the sensor inlet, keeping the sensor directly inline with fuel flow for accurate ethanol content readings at both high and low engine speeds.

With -10AN ORB outlets delivering ample flow volume for even the most extreme fuel systems, and compatibility with common GM flex fuel sensors, this is the clean, professional solution for E85 and flex fuel builds.

📌 Note: Recommended to be plumbed before the fuel rail for the most accurate ethanol content readings.
