In-Tank Fuel Pump Adapt. w/440LPH DW440 Pump

The In-Tank Fuel Pump Adapter with 440LPH DW440 Pump represents a critical upgrade path for high-performance engine builds and fuel-hungry modifications. Whether you're upgrading a naturally aspirated platform with forced induction, increasing fuel injector count, or pushing boost levels beyond factory fuel system capability, this adapter kit delivers the flow rate necessary to maintain safe fuel delivery under sustained high-load conditions. Designed by DeathschWerks, a recognized leader in fuel system engineering, this solution eliminates guesswork when retrofitting quality fuel pump hardware into factory or custom fuel tanks.

The 440-liter-per-hour flow rating of the integrated DW440 pump module addresses the threshold where stock fuel pumps fall short—typically above 350 wheel horsepower or when running lean boost maps. The adapter housing consolidates pump mounting, electrical integration, and fuel line routing into a precision-engineered assembly that mounts directly into most OEM fuel tank configurations. This design approach preserves tank integrity while ensuring consistent fuel pressure delivery across idle through wide-open throttle, critical for preventing lean-out conditions that damage pistons and detonation sensors on turbocharged or supercharged applications.

Mechanics and tuners working on domestic performance platforms, import drag builds, and street-driven forced induction vehicles will appreciate the bolt-in simplicity and elimination of aftermarket fuel cell requirements. Installation typically requires access from the top of the fuel tank; verify specific fitment against your vehicle's fuel sender configuration before ordering. The compact form factor—6.75 by 3.65 by 6.9 inches and weighing 2.2 pounds—ensures minimal chassis space impact while supporting fuel systems rated for 40+ PSI applications.
