OVERVIEW The Radium Engineering pump hanger is an excellent solution for increasing the fuel flow on modified 2011+ Ford Mustang vehicles. It can be used with 1 or 2 aftermarket pumps, with several pump options available. This drop-in unit replaces the OEM in-tank fuel pump module and is safe for use with alternative fuels such as E85. The Radium Engineering fuel pump hanger features a carefully designed collector box that keeps fuel trapped around the fuel pump(s). Inside, the fuel pumps are carefully packaged, along with the associated wiring and plumbing.  Fuel is fed out of the top plate through a single threaded port and low-profile adapter fitting. Fuel pressure is regulated inside the Radium hanger and is adjustable. The OEM fuel level sender is transferred onto the Radium hanger, so full functionality is retained. The OEM fuel tank access cover and rear seat bench fit without modifications.
