Radium Engineering 20-1070 Fuel Rail Honda D-Series Top-Feed Conversion

The Radium Engineering 20-1070 is a high-performance fuel rail designed as a direct-fit upgrade for Honda D-series engines. Engineered for enthusiasts and professional tuners who demand precision fuel delivery, this fuel rail supports top-feed injector configurations, enabling the use of larger, more capable injectors than the factory side-feed setup allows.

Radium Engineering manufactures this rail from billet aluminum, delivering superior strength, corrosion resistance, and a clean aesthetic compared to OEM plastic or stamped-steel components. The precision-machined construction ensures consistent fuel pressure across all injector ports, critical for even fuel distribution and optimal engine performance.

Key Features:

• Billet aluminum construction for maximum strength and durability
• Top-feed injector conversion for Honda D-series engines (D15, D16, etc.)
• Supports a wide range of aftermarket top-feed fuel injectors
• Precision-machined ports for consistent fuel pressure distribution
• Includes fuel pressure regulator mounting provision
• Anodized finish for corrosion resistance and clean appearance
• Direct bolt-on fitment for Honda D-series intake manifolds
• Compatible with high-horsepower fuel system builds

The Radium Engineering 20-1070 fuel rail is an essential component for any serious Honda D-series engine build, providing the reliability and flow capacity needed to support upgraded injectors and forced induction applications.
