Description

The DeatschWerks DW400 is an in-tank fuel pump designed for high-performance applications. It offers a flow rate of 415 liters per hour, supporting up to 1000hp on gasoline and 750hp on E85 fuel. The pump is ethanol-capable and includes a specific installation kit for the 2005-2010 Ford Mustang (excluding GT500 models).

DeatschWerks emphasizes the reliability, quiet operation, and cost-effectiveness of in-tank fuel pump placement. The DW400 aims to be a direct replacement for OE pumps, retaining benefits like low fuel level pickup and OE fuel line compatibility. The included kit contains necessary components such as hose, clamps, electrical harness, and filter, with step-by-step instructions often available.
