FITTINGS247 GM Continental Compact Flex Fuel Sensor
FITTINGS247 Billet Flex Fuel Sensor Bypass Adapter – -10 ORB (Suits GM / Continental E85 Sensors)
The FITTINGS247 Billet 2-Piece Flex Fuel Sensor Adapter is a high-performance bypass block designed for E85 / flex fuel systems, allowing seamless integration of a flex fuel sensor without restricting fuel flow.
Engineered for high horsepower and high-flow fuel systems, this adapter features a dual-channel bypass design that diverts a portion of fuel through the sensor while allowing the majority to flow unrestricted—maintaining maximum fuel pressure and volume.
Designed to suit genuine GM / Continental sensors, this unit is the ultimate solution for accurate ethanol readings in both feed and return fuel lines.
