Radium Engineering Ford Mustang Fuel hanger plumbing kits include everything required to install a return fuel system from the fuel pump hanger all the way to the engine bay. Radium Engineering port injection fuel rails can be purchased separately. All kits include 6AN PTFE fuel lines and three 8AN PTFE fuel lines.
Starting with the provided block-off kit for the integrated FPR and new feed and return fittings, a long 8AN PTFE feed line routes underneath the vehicle. Secured with 2 billet fuel/brake line retainers, this hose routes to a Radium Engineering check valve fuel filter mounted in a heat shield bracket. The 15-17 models use a Radium Engineering multi-port regulator (MPR). The 2018+ models (w/ direct and port injection) use a Radium Engineering dual fuel pressure regulator (DFPR). All adapters and fittings are included to connect to the direct injection HPFP and/or port injection fuel rail.
NOTE: The OEM fuel feel hard line is repurposed as a return line.
