Description
Radium Fuel Rail Plumbing Kit, Honda B / D / F / H-Series
Application: Honda B, D, F and H-Series engines with a Radium fuel rail
Part Type: Fuel rail plumbing kit
Part Number: 20-1270-PK
The Radium 20-1270-PK Fuel Rail Plumbing Kit connects a Radium Honda fuel rail to the factory feed with a 6AN hose. It is designed to be used with the factory fuel pressure regulator (FPR), although an aftermarket FPR can be used instead.
Two different FPR adapters are included so the kit suits all OEM Honda FPRs, along with plugs for any unused fuel rail ports and an adapter for the OEM pulse damper.
Key Features
- 6AN Feed: Easy connection to the factory feed with a 6AN hose and PushLok hose ends
- OEM FPR Adapters: Two different FPR adapters to suit all OEM Honda regulators
- Aftermarket FPR: An aftermarket regulator can be used instead of the factory unit
- Port Plugs: Plugs supplied for unused fuel rail ports
What's Included
- 8AN ORB to M12x1mm adapter (for a female-threaded OEM fuel pulse damper)
- 8AN ORB plugs for unused rail ports
- 2 x 6AN FPR adapter fittings (different flanges to suit all OEM Honda FPRs)
- 6AN adapter fitting for EGR-equipped engines
- 6AN male to M12x1.25mm adapter with crush washer (fuel filter outlet)
- 2 x PushLok hose ends
