Motion Raceworks In Line Flex Fuel Sensor Mount for use with E85 or Ethanol fuel systems to determine ethanol content.  This sensor is engineered with a dual channel flow through design to optimize flow, allowing flexibility for use in Feed OR Return lines.  This billet flow through component is internally optimized to flow MORE THAN a -10ORB or 10AN fitting.  This means that it can be truly used on a 10AN feed line without becoming a restriction in the system.  This offers peace of mind and performance advantages over running through the sensor only.
