Radium Engineering Fuel Pump Hanger | 2001-2006 Mitsubishi Evo 7/8/9 (20-1340/1342)

The 4G63 will make four-digit power on the stock tank, if the hanger stops being the bottleneck.

The factory Evo hanger was built for one modest pump and gasoline. The Radium Engineering Fuel Pump Hanger for the Evo 7/8/9 drops into the factory fuel tank replacing the OEM hold-down flange and carries 1 or 2 high-flow aftermarket pumps, with a single 8AN male pump feed port and 6AN male return port simplifying aftermarket AN plumbing while preassembled adapter fittings keep OEM line compatibility. Choose 20-1340 for the AEM 50-1220 or Deatschwerks DW440, or 20-1342 for the Walbro F90000267/274/285. Enough hardware ships for one or two pumps, so the hanger scales with the build. Pumps sold separately.

What You'll Feel

• Fuel supply headroom for E85 and big boost, up to dual 450-class pumps in the stock tank
• A true drop-in install replacing the OEM flange, no tank modification
• High-current confidence from sealed anti-rotation stainless electrical studs instead of fragile bulkhead pins
• Wiring tucked cleanly under the OEM cover plate thanks to the low profile design
• Either AN or factory-line plumbing from day one, with both fitting styles covered

Features

• Machined assembly drops into the stock Evo 7-8-9 tank, replacing the OEM hold-down flange
• Runs 1 or 2 pumps: 20-1340 fits AEM 50-1220 (and same form factor) and DW440; 20-1342 fits Walbro F90000267, F90000274, F90000285
• 8AN male pump feed port and 6AN male return port; preassembled adapters compatible with OEM fuel lines
• Anodized aluminum mounting plate, venturi jet pump with pressure relief valve, fluorosilicone duckbill return valve
• Anodized dual pump and fuel sensor bracket, submersible fuel lines, stainless hardware and clamps
• Sealed anti-rotation stainless electrical studs impervious to all standard and exotic fuels, with nonconductive acorn nuts preventing shorts

The Details

The internals show where the engineering went. The venturi jet pump with its pressure relief valve keeps the hanger's local reservoir fed from the far side of the tank, so hard cornering does not uncover the pickups, and the fluorosilicone duckbill valve manages return flow without adding restriction. Electrically, single or dual high-current pumps run through the sealed stud interface, and Radium's DIY wiring kits (one per pump, sold separately) complete the relay-and-fuse side. One system-level requirement decides your shopping list: this hanger eliminates the OEM unit's post-pump filter, so a low micron aftermarket filter must be installed downstream to protect the injectors, and Radium's Evo 7-8-9 fuel hanger plumbing kit includes exactly that filter along with the 8AN PTFE feed and return conversion. Pair with the Radium Evo rail, damper, and regulator for the full over-1,000 hp capable factory-tank system.
