Radium Engineering Fuel Hanger Plumbing Kit with Stainless Filter for Ford Mustang 2018+

Radium Fuel Hanger Plumbing Kit with Stainless Filter, Ford Mustang (2018+)

Application: Ford Mustang S550 (2018-2023) and S650 (2024+) – with Radium 20-180X hanger
Part Type: Fuel hanger plumbing kit (10 micron stainless filter)
Part Number: 20-1817-03

The Radium 20-1817-03 Fuel Hanger Plumbing Kit includes everything required to install a return fuel system from the Radium 20-180X fuel pump hanger all the way to the engine bay of the 2018+ Mustang. A new high-flow check valve fuel filter (10 micron stainless steel element that can be cleaned and reused), fuel lines, AN fittings and undercarriage fuel line retainers replace the OEM components, and the OEM feed hard line is repurposed as the return line.

Because 2018+ models use both port and direct injection, this kit uses Radium's dual fuel pressure regulator (DFPR), which can regulate pressure with boost at a 1:1 ratio if required, along with adapters for the direct injection high pressure fuel pump and port injection rail. Because the Radium hanger removes the in-tank low-micron filter, the external filter in this kit is required.
