Description
Radium Fuel Hanger Plumbing Kit with Microglass Filter, Cadillac CTS-V
Application: Cadillac CTS-V (2008-2015)
Part Type: Fuel hanger plumbing kit (6 micron microglass filter)
Part Number: 20-1325-05
The Radium 20-1325-05 Fuel Hanger Plumbing Kit is part of Radium's complete fuel delivery system for the 2008-2015 Cadillac CTS-V. It plumbs from the Radium 08-17 GM fuel pump hanger to Radium 20-0362 fuel rails, and its high-flow fuel filter (finer 6 micron microglass element), fuel lines, AN fittings and undercarriage fuel line retainer replace the OEM components.
Dual 6AN PTFE feed lines route from the fuel hat to the fuel filter, because a single 8AN line will not fit between the fuel tank and the unibody while two 6AN lines give a larger combined flow area. The back half of the OEM feed line is reused because it carries the OEM fuel pressure sensor needed for ECU diagnostics, and the stock feed line is repurposed as a 6AN return line.
Key Features
- Dual 6AN Feed: Two 6AN PTFE feed lines from the fuel hat to the filter
- OEM Sensor Retained: Reuses the back half of the OEM line with the factory fuel pressure sensor
- Return Line: Repurposed stock feed line becomes a 6AN return
- Check Valve Filter: Fuel filter incorporates a built-in check valve
- Filter Element: finer 6 micron microglass element
- Bolt-In Mounting: Anodised fuel filter bracket needs no permanent vehicle modifications
- Heat Protection: Thermal insulating sleeve protects against chafing and exhaust heat
