Designed specifically for use with the GM Continental ethanol content sensor used in most flex fuel applications.

The Visconti Tuning B58 S58 Flex Fuel Integration Fitting is designed to integrate a flex fuel sensor into the factory high pressure fuel pump hard line.

The fitting uses a 5/16 quick connect for the factory high pressure fuel pump hard line, a 3/8 quick connect for the flex fuel sensor.

This is NOT compatible with the factory fuel line.
