What is the flow rate of the DW400 fuel pump?

The DeatschWerks DW400 fuel pump is rated to flow 400 liters per hour. This higher flow rate is beneficial for modified engines that require more fuel than the stock system can supply.

What are PTFE fuel lines and why are they included?

PTFE (polytetrafluoroethylene) fuel lines are known for their excellent resistance to various fuels and high temperatures. Including them with the pump module ensures a durable and reliable fuel delivery system, especially in performance applications.

Does this fuel pump module come with everything needed for installation?

This is a pump module assembly that includes the DW400 pump and PTFE fuel lines. While it's designed for a direct fit in the factory location for compatible trucks, you should always refer to the manufacturer's instructions to confirm if any additional hardware or fittings are recommended for your specific setup.

Product Details

The DeatschWerks DW400 pump module features a robust internal pump capable of flowing 400 liters per hour, supported by PTFE fuel lines for reliable fuel delivery. This setup is designed to handle the demands of modified V8 engines found in popular trucks like the 1999-2004 Chevrolet Silverado and GMC Sierra models, including the 1500, 2500, and 3500 series. It's a well-built solution for those needing more fuel flow than stock, especially when upgrading other engine components.

This module includes the high-flow DW400 pump integrated into a complete module assembly, along with return-style PTFE fuel lines. PTFE, or polytetrafluoroethylene, is known for its excellent resistance to fuels and high temperatures, making these lines a durable choice for performance applications. The pump itself is a popular option for builds that require a significant increase in fuel volume, ensuring your engine receives adequate fuel under demanding conditions. The entire assembly is designed to fit within the factory fuel tank location for many 1999-2004 GM trucks, simplifying the installation process compared to universal inline pumps.

When you're pushing your truck's engine harder, whether through forced induction or other modifications, ensuring your fuel system can keep up is critical. This DeatschWerks module is a solid option for providing that necessary fuel flow. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for specific details regarding fitment and setup for your particular vehicle.
