The DeatschWerks X2 dual pump module is a direct-fit, drop-in fuel system upgrade for 2006-2013 BMW E8X and E9X chassis, including the 135i, 328i, 335i, M3, 1 Series M and X1. It houses two DW810 brushless in-tank fuel pumps, each rated at 810 lph, to deliver the high fuel volume required for E85, methanol and aggressive forced-induction tuning. The brushless motor design runs cooler and resists wear from ethanol and methanol far better than conventional brushed pumps, and the module installs in the factory fuel tank location using the included bulkhead harness and fitment hardware.
