OVERVIEW

The Radium Engineering adapter splits the fuel flow into an auxiliary passage parallel to the sensor. Because the flex fuel sensor is directly inline with the fuel flow path, it will read the incoming ethanol content at high and low engine demands. Traditionally this additional flow path could be accomplished with hose and y-adapter fittings. However, the Radium Split-Flow Flex Fuel Sensor Adapter is less complicated, considerably compact, and provides a mounting solution for many popular flex fuel sensors.

Flex fuel sensors measure ethanol content. They can be used in the FPR return line. But for improved accuracy and faster response times, the sensor should be plumbed upstream of the fuel injectors in the feed line. In this configuration, expect to see up to a ~10psi pressure drop if multiple pumps are used with a high-powered engine.

Fittings are not included and must be purchased to match your fuel line connection size and type. Unique 10AN ORB end port adapter fittings can be purchased HERE.
