Product Description

The Radium 20-1180 Fuel Pump Hanger is a high-performance in-tank solution engineered specifically for BMW E46 3-Series and M3 models built between 1998 and 2006. Designed as a direct drop-in replacement for the factory fuel hat assembly, this precision CNC-machined aluminum unit enhances fuel delivery reliability and supports one or two aftermarket fuel pumps (pumps sold separately). Integrated fuel pickup improvements - including a collector bowl and venturi pressure relief feature - help reduce starvation during cornering and high-G maneuvers, making it ideal for high-power naturally aspirated or forced induction builds. 

The 20-1180 hanger reuses the original passive and active fuel level sensors for accurate fuel gauge readings while simplifying plumbing via merged 10AN ORB ports. Its robust construction from lightweight CNC aluminum and stainless components provides long-term durability and corrosion resistance. This part supports a broad range of performance fuel pumps, allowing tuners and enthusiasts to tailor their fuel system for street, track, or competition use without modifying the vehicle's tank or wiring harness.
