DW420 Series 420lph In-tank Fuel Pump

The DW420 Series 420lph In-tank Fuel Pump by Deatschwerks is engineered for performance-oriented drivers and tuners who demand reliable fuel delivery under sustained high-load engine conditions. Whether you're running a naturally aspirated build pushing peak horsepower or a forced-induction platform requiring consistent fuel supply at elevated boost levels, this pump bridges the gap between stock limitations and serious power targets. Built for street and track applications, the DW420 Series eliminates fuel starvation concerns that plague stock pumps when engine demands exceed their design capacity.

Rated at 420 liters per hour (lph) at maximum output, this in-tank fuel pump delivers the volume and pressure stability modern fuel injection systems require when supporting 300+ hp engine configurations. The pump's internal design utilizes proven roller-gear technology that minimizes cavitation and maintains consistent flow across the entire operating range—critical for tuning precision and engine stability during wide-open throttle pulls. Its compact form factor and lightweight construction (1.155 lbs) allow for straightforward in-tank installation without requiring extensive fuel system modification or external pump mounting, reducing complexity while preserving factory tank integrity.

This pump suits enthusiasts upgrading fuel-injected vehicles across multiple platforms—from import sport compacts and domestic muscle cars to truck and SUV applications where increased displacement or forced induction demands exceed OEM fuel delivery. Installation requires basic mechanical competency and fuel system knowledge; users should verify pump compatibility with their specific vehicle's tank design, fuel line routing, and filter configuration before purchase. Pair the DW420 Series with quality fuel pressure regulators, in-line filters, and appropriately sized fuel lines to maximize reliability and achieve the precise fuel control needed for custom tuning.
