The Radium Engineering anodized aluminum adapter allows -6AN hose to be used with many OEM Toyota fuel pump housing outlets including Lexus, Scion, and Lotus 2ZZ-GE variations. This 1996 pump module design by Toyota is found on almost every model and is still used currently. We cannot confirm all vehicles so some research many need to be performed by the installer.  NOTE: if the vehicle uses this yellow locking clip shown, chances are this Radium Engineering adapter fitting will be compatible. Toyota Clip P/N: 77241-32060 is shown above with the Lotus 2ZZ-GE pump module. Toyota Clip P/N: 77241-33011 is shown below with the Lexus GS300/Toyota Aristo pump module. No modification to the fuel pump housing or vehicle is required. As shown below, the Radium Engineering adapter features an integrated O-ring for a leak-free positive connection.  The adapter fitting was designed to be ultra low-profile so the -6AN mating hose will have the best chance to fit underneath the OEM fuel pump access cover.    Instructions PDF
