Radium Fuel Pump Hanger, 2011+ Ford Mustang/Shelby suit Walbro GSS343/AEM 340lph

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.

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.
PREVENTING FUEL STARVATION
Several mechanisms work together to move fuel into the collector box and keep it full at all times. This ensures the pump(s) have adequate fuel available, even during aggressive driving. The internal pump(s) are supplied with fuel from 3 different sources: the venturi jet pump fuel scavenged from the passive side of the tank, the returned fuel from the integrated fuel pressure regulator, and the two 1-way fill valves on the bottom of the collector box (shown below). These valves allow fuel in, but not out. 

VENTURI JET PUMP
The OEM venturi jet pump in the return line creates a restriction when using high flowing fuel pumps. Radium Engineering has redesigned the siphon system to eliminate this restriction but still effectively scavenge fuel. This means higher flowing pumps can safely be used without fuel pressure issues. Depending on fuel pressure, the venturi jet pump will consume 15-45 LPH from the feed line. Take this fuel loss into consideration when sizing the fuel pumps. Connection to the crossover venturi system is made easy with the provided SAE quick connections (shown below).

Also, if it is important for fuel pressure to hold steady after the engine is shut down, install one of these CHECK VALVES somewhere in the fuel system.

INTEGRATED FPR
The Radium fuel hanger features an integrated adjustable fuel pressure regulator. This means a single feed line out (no return) that dead heads at the fuel rail, just like the OE system. This makes the system a simple plug-n-play install into a Mustang with the OE feed line. The built-in regulator is designed to handle the high flow rates of aftermarket pumps.

For vehicles with forced induction needing 1:1 rising rate fuel pressure, the built-in regulator features a vacuum reference. If an intake manifold vacuum hose is connected, the built-in FPR will operate at a 1:1 ratio permitting fuel pressure to proportionally increase with manifold (boost) pressure. Conversely, the vacuum port can remain open to atmosphere and pressure will remain constant (like OEM).
