OVERVIEW
This 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.

Part number 20-1322 (shown above) was designed specifically for the following Walbro 39/50 DCSS pumps: F90000267, F90000274, and F90000285.

All OEM sensors can be reused.

NOTE: There will be enough components included to use 1, 2, or 3 fuel pumps. Depending on the setup, some parts will simply not be used.


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. 

Additional 8AN ORB adapters fittings can be found HERE

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.


NOTES ABOUT FUEL PRESSURE SENSOR
There is an OEM fuel pressure sensor integrated to the feed line just downstream of the pump. This fuel hanger was designed to keep this pressure sensor operational. Simply connect the OEM fuel line to 1 of the 2 pump "OUT" ports. Also, SAE quick connect plugs are provided to cap off this OEM fuel line after this sensor, if need be.

NOTES ABOUT FUEL PRESSURE
1. This system eliminates the OEM fuel pressure regulator inside the stock unit.
2. This system requires the use of an aftermarket fuel pressure regulator
3. A fuel pressure regulator is included in the plumbing kit.


NOTES ABOUT FILTRATION
1. This system includes pre-pump filtration for all 3 pumps. 

As shown below, fuel cannot pass between the 3 independent filtration chambers (A, B, C). If less than 3 pumps are installed, the empty port does NOT need to blocked off.

2. This system eliminates the OEM "post" pump filter. A low-micron aftermarket fuel filter should be installed downstream to protect the injectors from debris.
3. A post-pump fuel filter is included in the plumbing kit.


NOTES ABOUT WIRING
1. Single fuel pump installations can re-use the OEM fuel pump controller wiring.
2. It is recommended to upgrade the wiring to ensure the pump(s) are operating at their full potential.
3. Universal fuel pump wiring kits can be found HERE. Select one for each aftermarket fuel pump used.



OPTIONS


20-1325-03/5 FUEL HANGER PLUMBING KIT, 08-15 CTS-V

VEHICLE COMPATIBILITY
08-15 Cadillac CTS-V

These fuel hanger plumbing kits are identical with one exception, the filter media:
P/N: 20-1325-03 uses a 10 micron stainless steel element.
P/N: 20-1325-05 uses a 6 micron microglass element.
More information on fuel filter elements can be found HERE.

The CTS-V plumbing kits feature dual 6AN PTFE feed lines that route from the fuel hat to the fuel filter. Two fuel lines are required here for the following reasons:
1. A single 8AN fuel line will not fit between the fuel tank and the unibody. The larger combined surface area of two 6AN lines fits nicely.
2. The back half of the OEM fuel line is reused. The stock fuel line incorporates the OEM fuel pressure sensor that is needed for ECU diagnostics.

The rest of the stock fuel line is repurposed as a 6AN return line (shown above). The kit includes an aluminum hose retainer bracket, as shown below.

The included fuel filter incorporates a built-in check valve. 

A thermal insulating sleeve is included to protect against chaffing and excessive exhaust heat. The anodized bolt-in fuel filter mounting bracket (shown below) does NOT require any permanent vehicle modifications.

As shown below, a clamp secures the PTFE fuel feed hose downstream away from the header. 

A high flowing 8AN PTFE fuel line from the fuel filter feeds the LH fuel rail (shown) and a 8AN crossover line connects the fuel rails at the front.

A fuel pressure regulator and pressure gauge mounts directly to the RH fuel rail. Radium Engineering 20-0362 fuel rails are required (sold separately).

The OEM feed line (now repurposed as the return) connects directly to the FPR return port, as shown above.

VEHICLE COMPATIBILITY
10-15 Camaro LS3/LS7/L99

These fuel hanger plumbing kits are identical with one exception, the filter media:
One kit uses a 10 micron stainless steel element.
One kit uses a 6 micron microglass element.
More information on fuel filter elements can be found HERE.

The Camaro plumbing kits feature dual 6AN PTFE feed lines that route from the fuel hat (shown above) to the fuel filter (shown below).

Two fuel lines are required here for the following reasons:
1. A single 8AN fuel line will not fit between the fuel tank and the unibody. The larger combined surface area of two 6AN lines fits nicely.
2. The back half of the OEM fuel line is reused. The stock fuel line incorporates the OEM fuel pressure sensor that is needed for ECU diagnostics.

The rest of the stock fuel feed line is repurposed as a 6AN return line. The kit includes 4 green anodized hose retaining adapters with clamps (depicted above). The included fuel filter (shown below) incorporates a built-in check valve. 

The Camaro-specific fuel filter mount does NOT require any permanent vehicle modifications. As shown below, a thermal insulating sleeve is included to protect against chaffing and excessive exhaust heat. 

As shown below, a billet aluminum clamp secures the 8AN PTFE hose downstream away from the header. 

The 8AN PTFE line from the fuel filter feeds the RH fuel rail. A fuel pressure regulator and pressure gauge mounts directly to the LH fuel rail. Radium Engineering fuel rails and fuel rail plumbing kits are required (sold separately).

A 6AN PTFE fuel line is provided that connects the FPR return port to the OEM fuel feed hard line.
