DeatschWerks DW400 Performance Pump Module for 15-21 WRX

The DeatschWerks DW400 fuel pump module is built with a robust turbine impeller design, which helps ensure consistent fuel delivery even under demanding conditions. This pump is a popular choice for Subaru WRX owners looking to support increased horsepower and torque, especially when upgrading other engine components like the turbocharger or exhaust system. It’s designed to fit directly into the factory fuel tank assembly, making the installation process more straightforward for those familiar with fuel system work.

This module is rated to flow 400 liters per hour at 40 PSI, which is a significant increase over the stock pump's capacity. This higher flow rate is crucial for maintaining proper fuel pressure when your engine is consuming more fuel. The DW400 uses a 300-micron inlet filter to help keep debris out of the pump mechanism, and it comes with a quiet, low-amp draw motor that won't add unnecessary noise to your cabin or drain your battery. It’s a well-built unit designed for reliability and performance.

When installing this fuel pump module, it’s important to ensure all connections are secure and that the pump is properly seated in the fuel tank. While it’s designed as a direct replacement, always refer to the manufacturer's installation instructions for specific details. This pump is not CARB approved, so it cannot be shipped to California. It's a solid option for WRX owners aiming to build a more powerful and responsive engine.
