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. FEATURES Drop-In Installation Permits 1 or 2 Pumps  Integrated 1: 1 Adjustable FPR Fuel Starvation Protection High Current Electrical Hardware Compatibility with Popular Fuel Pumps Anodized Aluminum Construction Gasoline, Methanol, Ethanol Compliant Fuel Resistant Tubing and Wiring Stainless Steel Hardware New Anti-rotation Electrical Terminals IMPORTANT NOTE: This fuel pump hanger is only sold without pumps pre-installed. Pumps must be installed by the end user/installer. Refer to the installation instructions linked above. Pumps may be purchased with the hanger, but they will not be pre-installed. PUMP COMPATIBILITY To choose the correct fuel hanger version, first determine what fuel pump(s) will be use, see below. Once fuel pumps are decided, select the fuel pump hanger part number that is compatible with the chosen pumps. NOTE: Fuel pumps are sold separately.  20-1801 Ti BKS1001 (brushless) NOTE: Because the brushless E5LM fuel pump does not have an integrated check valve, P/N: 20-0801-00 contains two bolt-on check valves. This permits pump staging which is common when using multiple fuel pumps.  Instruction PDF
