Fitment Notes

• Designed specifically for BMW F-chassis platforms using N20 (4-cyl turbo) and N55 (6-cyl turbo) engines only - does not fit N54, S55, B58, or other engine variants.
• This module integrates the OEM returnless low-pressure fuel line and retains all factory connections - no fuel system conversion required.
• Retains the OEM fuel level sensor, filtration capacity, and surge protection - full plug-and-play installation with no cutting, splicing, or modification needed.
• A 10-gauge hardwire kit (DeatschWerks PN# FPHWK-10-HD) is strongly recommended to ensure maximum voltage at the pump for optimum performance.

Features

• 415lph flow rate delivers 80% more fuel than the OEM F30/F20/F87 factory module - the highest-flow drop-in low-pressure module available for these platforms.
• True plug-and-play installation - module consists of a top-hat, center section, and lower bucket that drop directly into the OEM fuel tank housing without any modification.
• Retains the factory OEM returnless fuel line interface, fuel level sender, and all OEM harness connections - no return-style plumbing conversion required.
• DW400 composite turbine impeller is fully E85 and ethanol blend compatible - carbon commutators and an encapsulated armature provide long-term ethanol resistance.
• Low NVH operation via computer-balanced armature and turbine impeller design - quieter than rotor-style pump alternatives.
• PWM (Pulse Width Modulation) compatible - works with OEM and aftermarket fuel demand controllers for efficient voltage-based pump speed management.
• Rated to 120 psi total fuel pressure - supports forced induction builds well beyond stock power levels.
• Backed by DeatschWerks' 3-year no-fault warranty.

Product Description

The DeatschWerks 9-421-7270 is a direct drop-in DW400 fuel pump module engineered for BMW F-chassis vehicles running N20 and N55 engines. Flowing 415lph - 80% more than the factory module - this kit is the definitive low-pressure fuel system upgrade for 2-series, 3-series, 4-series, and M2 builds pushing beyond what the OEM fuel system can support. Unlike many high-flow pump solutions, the 9-421-7270 integrates the factory returnless fuel line interface and retains all OEM connections, making it a genuine plug-and-play upgrade with no fuel system re-plumbing required.

The module's three-piece design - top-hat, center section, and lower bucket - installs directly into the OEM fuel tank without any modification. The factory fuel level sensor, harness, and filtration are all retained, so the car's fueling system operates exactly as intended. The DW400 pump inside features carbon commutators and a fully encapsulated armature for complete E85 compatibility, making this module equally suited for builds running ethanol blends or straight E85. Whether you're running a modified N55 335i, a boosted M235i, or building a track-focused M2, the 9-421-7270 provides a clean, reliable foundation for serious fuel system upgrades.
