Radium - Multi-Pump Fuel Surge Tank (Triple Pump Capable)

The Radium Engineering Multi-Pump Fuel Surge Tank (MPFST) is the premier fuel surge tank solution for extreme horsepower applications. Specifically engineered to prevent engine-damaging fuel starvation during aggressive road racing, drifting, or drag launches, this high-capacity surge tank can house up to three internal high-flow fuel pumps within a single compact 2.2-liter aluminum vessel.

Key Performance Features:

• Configurable for 1, 2, or 3 Fuel Pumps: All kits include Radium block-off plugs and terminal seals, allowing builders to run a single primary pump, staged dual pumps, or all three pumps simultaneously.
• Individual Pump Circuits: Triple isolated electrical pass-through studs allow standalone wiring and staged ECU activation for each pump.
• Dual Merged Outlets: Pump outputs are internally manifolded into massive -10AN ORB outlet ports for high flow without external Y-blocks.
• Anti-Starvation Architecture: Internal baffling keeps the fuel pump pickups continuously submerged even at very low main tank levels.
• Precision Machined: CNC machined from 6061 billet aluminum, Type-II anodized black and green, and fully E85 / race gas compatible with FKM O-ring seals.

Pump Compatibility Configurations:

• 20-1440: Precision machined for standard 39mm body pumps (Walbro GSS342, AEM 50-1000/1200, DeatschWerks DW200/DW300, DW440 Brushless).
• 20-1441: Precision machined for 46mm body pumps (Bosch BR540, DeatschWerks DW400).
• 20-1442: Precision machined for flared-base pumps (Walbro 450 / 525 Hellcat, F90000267 / 274 / 285 / 295).
• 20-0443-00: Precision machined for TI Automotive E5LM Brushless fuel pumps.

Note: Fuel pumps, plumbing hoses, and fuel level switches are sold separately. Includes 1/8" NPT port for optional low-fuel level switch.
