Radium Engineering Fuel Pump Hanger – Subaru WRX/STI 1993–2007

The Radium Engineering fuel pump hanger is a high-performance solution for Subaru vehicles using the EJ platform. Designed to fit directly into the factory fuel tank, this billet aluminium assembly supports one or two aftermarket fuel pumps and retains the OEM fuel level and temperature sensors. No permanent modifications are required.

This system merges both pumps into a single 8AN ORB outlet. Return and crossover lines use 6AN ORB ports. To simplify installation, the kit includes fittings to suit OEM fuel hoses (including SAE quick-connects) and -6AN male adapters for aftermarket plumbing.

An integrated venturi jet pump with pressure relief and a 355LPH one-way fill valve ensures consistent fuel delivery. The low-profile collector box keeps the pump(s) submerged, reducing starvation under hard driving.

Electrical hardware includes anti-rotation stainless terminals, ETFE-insulated wiring, and heat-shrink ring terminals for secure connections. OEM wiring can be reused for single pump setups, but upgraded wiring is recommended for dual pumps.
