DW300M Electric Fuel Pump In-Tank 340LHP

The DW300M Electric Fuel Pump In-Tank 340LHP by Deatschwerks is engineered for serious enthusiasts and professional tuners who demand reliable, high-flow fuel delivery in modified and turbocharged vehicles. Whether you're running aggressive boost levels, multi-stage nitrous, or pushing your engine beyond stock fuel system capacity, this in-tank pump eliminates fuel starvation and enables consistent performance from idle to redline. Built to fit inside your factory fuel tank, it replaces the OEM pump without requiring extensive modifications, making it a practical upgrade for street cars, track vehicles, and full competition builds.

At 340 liters per hour (LHP) flow capacity, the DW300M delivers volume and pressure consistency that stock fuel systems simply cannot match, especially under sustained high-load conditions. The pump's electric brushless motor runs quieter and cooler than conventional designs, reducing heat rejection into the fuel tank and minimizing vapor lock issues common in forced-induction applications. Its compact 4.25 x 2.35 x 6.5 inch profile and 1.67 lb weight allow straightforward installation within most OEM fuel tank assemblies, while the sealed, submersible design protects internal components from fuel degradation and corrosion over extended service intervals.

This pump is ideal for turbocharged four-cylinder engines, high-displacement naturally aspirated builds, and any platform requiring fuel flow beyond 255–280 LHP thresholds. Installation requires basic fuel system knowledge and compatible fuel lines; verify tank fitment and electrical harness compatibility with your specific vehicle platform before ordering. The DW300M pairs seamlessly with aftermarket fuel injectors, stand-alone ECUs, and tuning software, making it a go-to choice for shops and builders tackling comprehensive fuel system upgrades.
