Radium BMW E46 Fuel Pump Hanger

Application: BMW E46 3 Series incl. M3 and M3 CSL (OEM BMW/VDO level senders required) Part Type: Dual-side fuel pump hanger (one or two pumps, pumps sold separately) Part Number: 20-1180

The Radium 20-1180 replaces both the left and right-side fuel hat assemblies in the BMW E46 saddle tank. It runs one or two aftermarket fuel pumps, reuses the OEM passive and active fuel level sensors and retains a true saddle-tank crossover – with no cutting or modification to the vehicle.

The collector bowl is fed from three sources: the OEM labyrinth, low-pressure return fuel driving the venturi siphon, and crossover fuel scavenged from the passive side. A redesigned PRV venturi jet pump with built-in pressure relief valve limits excess return flow, which can otherwise pop the OEM connection when high-flow pumps run at low load, and allows low static fuel pressure.

Key Features

One or Two Pumps: Supports one or two aftermarket pumps, brushed (2-wire) or brushless (3/4-wire)
OEM Sensors Retained: Reuses the OEM passive and active fuel level sensors
Saddle Tank Crossover: True crossover retained, with three-source collector bowl feed
PRV Venturi Jet Pump: Built-in pressure relief valve protects the OEM connection and allows low static pressure
Fittings: Merged pump outlet and return inlet tapped 10AN ORB (7/8"-14), with SAE quick-connect barb to the OEM feed line and 8.5mm barb to the OEM return line
Electrical: Hermetically sealed anti-rotation stainless studs, anodised aluminium acorn nuts and ETFE-insulated in-tank wiring
No Modification: Drop-in installation with no cutting or modification

What's Included

Feed-side and return-side hanger tops, partially assembled
