Radium - Universal Fuel Surge Tank for External Pumps

The Radium Engineering Universal Fuel Surge Tank for External Pumps is designed specifically for competition applications where builders prefer to mount external inline fuel pumps (such as Bosch 044, AEM 50-1005, or Weldon pumps) outside the surge tank. Extruded and CNC machined from 6061-T6 aluminum, this 1.5-liter canister ensures continuous fuel supply to high-draw external pumps.

Key Performance Features:

• Dual High-Flow Pickups: Features dual -8AN ORB bottom outlets positioned to feed one or two external fuel pumps with zero suction restriction.
• 1.5-Liter Buffer Capacity: Keeps external pump inlets flooded even during prolonged high-G lateral cornering on track.
• Internal Baffling: Directs aerated return fuel away from the bottom pickups to prevent air ingestion.
• Multi-Port Top Cap: Top cap provides dedicated -6AN ORB ports for lift pump feed, fuel rail return, and overflow to main tank.
• E85 / Race Fuel Rated: Mil-spec black anodizing protects against corrosive fuels and harsh environments.

Notice: Inlet and outlet ports are female ORB; male AN adapter fittings, hose ends, and external pumps are sold separately.
