The RADIUM Engineering 20-1972 Fuel Hanger Surge Tank (FHST-RA) is a revolutionary in-tank solution to eliminate fuel starvation during high-performance driving while providing the ability to upgrade to high-flow aftermarket fuel pumps. This system is installed inside the BMW fuel tank on the opposite side of the factory fuel pump and can hold one or two high-flow aftermarket fuel pumps.

Key Features:

• Compatible with Walbro F90000267, F90000274, or F90000285 E85 fuel pumps (pumps sold separately)
• Collector box and built-in pressure regulator included
• The stock fuel pump is used to pump fuel into the FHST, while the pumps inside the FHST then supply fuel to the engine
• Integrated fuel pressure regulator can operate at a 1:1 ratio permitting fuel pressure to proportionally increase with boost pressure
• 6-hole diverter evenly disperses fuel inside the canister preventing air bubbles and foaming
• E85 compatible and does not require any permanent modifications for installation
