| Brand: | Radium Engineering |
| CARB Approved: | No |
The Radium Engineering 20-1070 Fuel Rail is a CNC-machined fuel delivery component designed for Honda D-Series engines using OEM intake manifolds. It fits the stock fuel rail mounting locations and provides a durable, performance-focused upgrade for street, track, and competition fuel systems. The rail is compatible with Honda Civic applications from 1985 through 1999, including models equipped with D-Series engines.
Both ends feature 8AN ORB ports for flexible fuel system plumbing, while two additional auxiliary ports on the top surface allow installation of a Radium Engineering Fuel Pulse Damper or another compatible fuel system accessory. This configuration supports a variety of fuel system layouts and makes it easier to tailor the rail to custom engine bay and fuel delivery requirements.
The 20-1070 is compatible with stock Honda fuel injectors and aftermarket injectors that use similar fitment. It can also be used with aftermarket intake manifolds that retain the OEM fuel rail mounting locations. CNC machining provides precise injector and mounting alignment, helping ensure reliable installation when paired with the correct injector configuration and hardware.
Installation instructions are available at RadiumAuto.com. This product is intended for automotive applications and is not CARB-approved. Verify injector compatibility, intake manifold mounting provisions, and applicable emissions regulations before installation.
