Overview

Nissan R33 Skyline (All models/trims/RHD/LHD)

Nissan R34 Skyline (All models/trims/RHD/LHD)

Upgrade your factory fuel system with the Radium Engineering 20-0630-00 Fuel Hanger, designed for select late-model Nissan applications. This high-performance fuel pump hanger supports one or two in-tank fuel pumps, making it an ideal solution for high-horsepower street, drag, drift, and motorsport vehicles running gasoline, E85, or methanol.

Engineered from CNC-machined anodized aluminum, the fuel hanger features a restriction-free fuel return system, integrated venturi jet pump siphon, and high-current electrical terminals designed to support both traditional and brushless fuel pumps. Factory fuel lines can be retained using the included OEM-style adapter fittings, eliminating the need for additional fuel plumbing on stock fuel systems.

Why Upgrade to the Radium Fuel Hanger?

The factory fuel system can become a limitation as horsepower increases. The OEM venturi jet pump often creates excessive return-line restriction when paired with high-flow aftermarket fuel pumps, leading to unwanted backpressure and inconsistent fuel pressure.

The Radium 20-0630-00 Fuel Hanger eliminates this restriction with a redesigned siphon system that continues transferring fuel between tank chambers while allowing unrestricted fuel return. Combined with support for dual pumps and brushless fuel pumps, it provides a reliable fuel delivery solution for demanding performance applications.

Installation Notes

• Direct drop-in replacement
• Factory fuel lines can be reused using the included adapter fittings
• Low-profile AN swivel fittings are required when using aftermarket AN fuel lines
• Straight AN fittings may interfere with the factory access cover
• Single pump installations can reuse the factory fuel pump controller wiring
• Upgraded fuel pump wiring is recommended to maximize pump performance
• Depending on fuel pressure, the venturi jet pump consumes approximately 15–45 LPH
• A fuel system check valve is recommended if maintaining residual fuel pressure after engine shutdown is desired
