20-1325-03

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).
