Radium Fuel Hanger For Walbro F90000267/274/285 - Pumps Not Included | 2013-2021 BRZ/FR-S/86 (20-1073)

The FA20 tank was designed for 200 horsepower; twin Walbro 450s are a different conversation entirely.

The Radium Engineering Fuel Pump Hanger for the FR-S / BRZ / 86 replaces the factory in-tank pump assembly with architecture built for real power: 1 or 2 pumps in the stock tank, merged into a single 8AN ORB outlet with an 8AN male pump-out fitting, a 6AN ORB return with 6AN male fitting, and a 1-piece anodized aluminum collector box with 1-way fill valve and venturi jet pump siphon keeping fuel trapped around the pump inlets to prevent starvation. This 20-0573-00 version fits the Walbro F90000267, F90000274, and F90000285, plus the brushless DW440, Fuelab 49614, and Protec 11928. High current electrical connections, an anodized fuel level sender mount, stainless hardware and clamps, and alternative fuel compatibility complete the assembly. Pumps sold separately; enough components are included for 1 or 2 pumps.

What You'll Feel

• Fuel delivery scaled for turbo and supercharged FA20 builds, up to twin 450-class or brushless pumps
• Starvation resistance from the collector box, fill valve, and venturi siphon working the corners
• A single merged 8AN outlet simplifying feed plumbing regardless of pump count
• Full-power pumps through high current electrical connections, not pinched factory wiring
• The factory fuel level sender retained on its anodized mount

Features

• Runs 1 or 2 pumps in the factory tank; 20-0573-00 fits Walbro F90000267/274/285 and brushless DW440, Fuelab 49614, Protec 11928
• 8AN ORB merged outlet with 8AN male pump-out fitting; 6AN ORB return with 6AN male fitting
• 1-piece anodized aluminum collector box with 1-way fill valve and venturi jet pump siphon
• High current electrical connections; anodized fuel level sender mount; stainless hardware and clamps
• Sock filters provided for the Walbro pumps; brushless pumps use their manufacturer-included socks
• Alternative fuel compatible including E85; pumps NOT included

The Details

The collector box is the anti-starvation core, a one-piece anodized reservoir keeping the pump inlets submerged while the venturi siphon actively pulls fuel toward them, which matters on a chassis that generates its cornering loads so easily. Pump notes follow the family rules: the Walbro trio drops in with the provided socks, the brushless options require their manufacturers' controllers, and every pump wants a Radium DIY wiring kit so current matches flow. The companion 20-0306 plumbing kits (sold separately, manual transmission only) convert the OEM returnless system to a true return system with filter, regulator, and gauge, completing the fuel delivery system Radium designed as a set. Fitment spans the FA20 twins and, per Radium's current listing, the GR86 generation.
