DeatschWerks Fuel Pump

DeatschWerks Fuel Pumps: Engineered Flow for Every Build

When a forced-induction engine demands more fuel than the factory pump can supply, tuners and racers around the world reach for a DeatschWerks pump. Fuel pumps are the unsung heart of any high-performance fuel system, and DeatschWerks has spent over a decade refining exactly what it takes to keep up with modern engine builds — from bolt-on street cars to full race machines.

A Pump Lineup Built Around Flow at Pressure

Most fuel pumps are rated at a low, standard test pressure — a number that flatters but doesn't reflect real-world forced-induction conditions. DeatschWerks engineered their pumps differently. By designing the armature for torque bias, delaying pressure relief activation, and maximizing impeller efficiency, DW has created a line of pumps with an extremely flat flow curve — meaning they maintain strong output even as system pressure rises under boost.

The DW pump lineup covers a wide range of applications and power levels:

• DW200 (255 LPH): A compact, low-current in-tank pump supporting 400–600 HP. Features a turbine impeller compatible with pulse-width-modulated pump drivers and an encapsulated armature for ethanol compatibility.
• DW300 (340+ LPH): The pump that started it all — when DeatschWerks entered the pump market in 2009, the DW300 became the first in-tank fuel pump to outflow the standard 255 LPH benchmark.
• DW420 (420 LPH): Flows 420 LPH at 40 PSI, making it a go-to choice for high-demand ethanol applications or any build that needs the highest flowing standard-fitment in-tank option available.
• DW810 Brushless: The brushless motor technology in the DW810 reduces friction and heat, vastly improving durability — especially when running aggressive fuels such as ethanol and methanol.
• Inline Pumps (250iL / 350iL): For external mounting or custom fuel system builds, these inline units utilize roller-vane technology for a flatter flow curve and feature O-ring fittings to easily accommodate larger fuel lines.

Ethanol-Ready by Design

As E85 and high-ethanol blends have become increasingly common on the street and strip, DeatschWerks built compatibility in from the ground up. Composite impellers resist ethanol's corrosive nature, while fully encapsulated motor armatures protect copper windings from deterioration — details that matter greatly for long-term reliability on aggressive fuel blends.

Application-Specific Fitment Kits

One of DeatschWerks' most practical advantages is their fitment system. Each pump ships with an application-specific kit — the correct O-rings, electrical connectors, clamps, filters, and spacers — so the pump installs directly into the OEM module without modification. DW maintains a library of over 100 OE fuel pump modules to source these kits, and every combination is bench-tested before a part number is published.

Validated Through Rigorous Testing

Before any DW pump reaches production, it goes through 1,000 hours of endurance bench testing across multiple fuel types to identify and eliminate failure modes. After that, it undergoes several months of real-world in-car testing. Each individual pump is then flow-tested at pressure before it is labeled and packaged — a level of quality assurance that few aftermarket suppliers match.

Whether you are building a Sport Compact track car, a Modern Muscle street/strip machine, or a Euro-spec turbocharged build, the DeatschWerks fuel pump lineup offers a validated, drop-in solution engineered to deliver the flow your engine demands.
