Frequently Asked Questions
What Honda engine series does the RAD20-1270-PK work with?The RAD20-1270-PK is designed for Honda B series, D series, F series, and H series engines. Confirm compatibility with the specific Radium fuel rail for your engine family before ordering.
Is this kit required when installing a Radium Engineering fuel rail?Yes. The RAD20-1270-PK provides all the plumbing components needed to connect a Radium fuel rail to the existing Honda factory fuel system hard lines. Without this kit, the installer would need to source each fitting, hose, and adapter individually to complete the connection.
Does the RAD20-1270-PK work with aftermarket fuel systems or only factory Honda lines?The RAD20-1270-PK is designed to bridge the Radium fuel rail to the factory Honda fuel system lines. Use with heavily modified or fully custom fuel systems may require different adapter fittings not included in this kit. Confirm your specific fuel system configuration with Radium Engineering before ordering.
Is the RAD20-1270-PK compatible with forced induction Honda builds?The RAD20-1270-PK itself is a plumbing adapter kit. Whether the complete fuel system supports forced induction depends on the fuel rail, injectors, and fuel pressure regulator selected for the build. Consult Radium Engineering directly for high-flow forced induction fuel system recommendations.
Can the RAD20-1270-PK be used with the Honda K series engine?No. The RAD20-1270-PK is specified for Honda B, D, F, and H series engines. K series engine applications use a different Radium fuel rail and corresponding plumbing kit. Check Radium Engineering's current product catalog for the correct K series plumbing kit.
What fuel hose material is used in the RAD20-1270-PK?Radium Engineering specifies components to meet the pressure and chemical compatibility requirements for fuel system use. For exact material specifications on the hoses and fittings included in the RAD20-1270-PK, refer to Radium Engineering's product documentation or contact them directly.
Does the RAD20-1270-PK include a fuel pressure regulator or fuel rail?No. The RAD20-1270-PK is a plumbing kit only and does not include a fuel rail or fuel pressure regulator. It is intended to be purchased alongside the appropriate Radium Engineering fuel rail for your Honda engine series.
Is professional installation recommended for the RAD20-1270-PK?Fuel system work involves flammable liquids under pressure. Professional installation is strongly recommended. Ensure the engine is cold and the fuel system is depressurized before beginning any fuel rail plumbing work.
Installation Notes
- Confirm the engine is cold and the fuel system pressure has been relieved before beginning work.
- Identify the factory Honda fuel system inlet and return hard line connections in the engine bay for your specific engine family (B, D, F, or H series).
- Install the Radium Engineering fuel rail on the engine following the Radium fuel rail instructions.
- Use the adapter fittings from the RAD20-1270-PK to connect the Radium fuel rail ports to the fuel hoses included in the kit.
- Route and connect the fuel hoses to the factory Honda hard line fittings using the appropriate adapters from this kit.
- Check all connections for leaks before starting the engine. Start the engine and recheck all fittings under pressure before returning the vehicle to service.

Fuel Delivery
A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential. Popular Upgrades Top-selling fuel delivery components include Aeromotive Phantom in-tank fuel pump kits that retrofit into factory tanks without custom fa...

Fuel Pump Hangers
Fuel pump hangers, also called pickup assemblies or pump hats, are the structural component that suspends the fuel pump inside the tank and positions the pickup tube at the correct depth for consistent fuel delivery under all vehicle attitudes including hard acceleration, braking, and cornering. In custom fuel cell builds, the hanger must be fabricated or selected to match the cell's depth and internal dimensions, with the pickup tube length and anti-surge baffle positioning designed around the vehicle's expected dynamic load conditions. Factory replacement hangers restore the OEM geometry and fuel level sender calibration when replacing a failed pump module, while performance hangers from Aeromotive and Holley allow custom positioning of high-flow pump bodies that are larger than the factory module housing. Getting the hanger geometry right eliminates the fuel starvation issues that appear during hard cornering or sustained high-speed running when poorly positioned pickups uncover ...
