Radium Engineering Fuel Hanger AEM 50-1220 DW440 Cadillac CTS/CTS-V 08-14 - Pumps Not Included

Radium Engineering GM fuel hanger completely replaces the factory in-tank fuel pump module and allows 1, 2, or 3 aftermarket pumps to be used.

Part number 20-1320 (shown above) was designed specifically for AEM 50-1220 pumps as well as the brushless Bosch pumps found in the Deatschwerks DW440 kits.

*No internal check valve. Best to run 2 full time with the OEM PCM.


NOTES ABOUT FUEL STARVATION
1. The 1-piece anodized aluminum collector box keeps fuel trapped around the pump inlet(s).
2. There are three 1-way fill valves incorporated in the bottom of the collector box that allows fuel in, but not out. Each 1-way fill valve flows 355 LPH.
3. The collector box is constantly replenished with fuel returning from the pressure regulator.
4. The collector box is constantly replenished with fuel coming from the jet pump crossover line.


NOTES ABOUT PORTS AND FITTINGS
1. There are 2 pump "OUT" ports that are both tapped with 3/4"-16 (8AN ORB) threads.
a. The first "OUT" port can be used to reconnect the factory fuel feed line. Because the OEM fuel feed line has an integrated fuel pressure sensor, this feature is critical for many applications. There are 2 different SAE quick connect fittings provided to adapt to the specific vehicle.
b. The second "OUT" port can be used to route another feed line for increased flow. This port comes preinstalled with an 8AN ORB plug but a spare 8AN ORB to 6AN Male fitting is provided.

2. The "RETURN" port is tapped with 3/4"-16 (8AN ORB) threads. Provided is an 8AN ORB to 6AN Male banjo fitting.

NOTES ABOUT THE VENTURI JET PUMP
1. The OEM venturi jet pump in the return line creates a restriction that can impact fuel pressure reliablity.
2. The siphon system has been replaced and redesigned to eliminate this return line restriction but still effectively scavenges fuel. This means higher flowing pumps can safely be used without fuel pressure issues.
3. Depending on fuel pressure, the venturi jet pump will consume 15-45 LPH. Take this fuel loss into consideration when sizing the fuel pumps.
4. To reconnect the internal OEM fuel crossover transfer line, 2 different SAE quick connect fittings are provided to cover all compatible vehicles.
5. The fuel pump hanger plumbing kits (listed below) include fuel filters with a built-in check valve. If not purchasing one of these plumbing kits and it is important for fuel pressure to hold steady after the engine is shut down, install one of these check valves in your fuel system.

NOTES ABOUT FUEL FEED LINE
One of the "OUT" ports can be used to reconnect the factory fuel feed line. Because the OEM fuel feed line has an integrated fuel pressure sensor, this feature is critical for many applications.

There are 2 different SAE quick connect fittings provided to adapt to the specific vehicle.

NOTES ABOUT FUEL LEVEL SENSOR
To retain the OEM fuel level sensor, 2 different billet aluminum mounts are provided to cover all compatible vehicles.
