The Mk4 Toyota Supra Radium Engineering fuel brake line retainer kit supports larger aftermarket fuel lines under the MKIV (JZA80) Toyota Supra. This is our go-to kit for all of our Mk4 Toyota Supra fuel system builds. The (4) included retainers are made from 6061 aluminum and anodized in Radium green. This kit utilizes the OEM studs and hardware and no drilling is required. Don't trust your car or fuel system to just zip ties!
