Product Description

The Radium 20-1270-PK is a fuel rail plumbing kit designed to connect a Radium fuel rail on Honda B, D, F, or H-series engines to the factory fuel feed line at the OEM fuel filter. Rather than sourcing individual hoses and fittings, this kit bundles everything needed for a clean, straightforward hookup in one package.

The kit includes an FPR adapter so it interfaces directly with the factory fuel pressure regulator, while also remaining compatible with an aftermarket regulator if you've upgraded that part of your fuel system. Pushlok hose ends provide secure, leak-resistant connections, M12 and 6AN/8AN ORB adapters cover the fitting transitions between OEM and aftermarket hardware, and 8AN ORB plugs let you cleanly cap off any unused rail ports.

This is a plumbing kit only - you'll need to pair it with the appropriate Radium fuel rail for your specific engine family (B-Series, D-Series, F-Series, or H-Series) to complete the fuel system upgrade.
