This Radium Engineering fuel pump hanger is a drop-in, in-tank surge tank that holds one to three aftermarket pumps (pumps not included) and is configured for Walbro F90000267, F90000274 and F90000285 pumps. A one-piece anodized aluminum collector box surrounds the pumps and is fed by an integrated venturi jet pump and three one-way fill valves to prevent fuel starvation under hard cornering and acceleration. It can run as a surge tank, in a merged hanger setup, or with isolated direct injection and port injection systems, has a 10AN ORB feed port with a low-profile 8AN fitting and a 6AN ORB lift pump port, and is E85 compatible. Walbro F90000295 pumps also fit but require a 20-1534 check valve per pump, and Protec 11928 or Fuelab 49614 pumps require the 13-1187 strainer base. The hanger installs on the side opposite the OEM pump module, which stays in place; installation requires removing the rear subframe and drivetrain to access the tanks.
