What is the flow rate of the DW400 pump?

The DW400 pump is known for its high flow rate, designed to support significantly more fuel than a stock pump. Specific flow rate figures depend on system pressure, but it's engineered for performance applications.

Does this kit include everything needed for installation?

This kit includes the DW400 pump module and PTFE fuel lines. It is designed as a replacement for your factory fuel pump assembly. Refer to manufacturer instructions for any additional hardware or sealants that may be recommended for your specific installation.

Is this fuel pump module compatible with E85 or other alternative fuels?

The included PTFE fuel lines are resistant to many modern fuel blends. However, this specific kit excludes Flex Fuel applications, so it's important to confirm compatibility with your intended fuel type and consult DeatschWerks for detailed fuel compatibility charts.

Product Details

If you're looking to upgrade the fuel system on your 2005-2013 Chevrolet Silverado 1500 or GMC Sierra 1500, this DeatschWerks DW400 pump module is a solid option. This unit is designed to handle increased fuel demands, making it a popular choice for modified trucks or those pushing their engines harder. It replaces your factory fuel pump assembly with a higher-flow unit and includes PTFE fuel lines for a complete upgrade.

The DW400 pump itself is known for its ability to move a lot of fuel, which is crucial when you're adding performance modifications that require more fuel than stock. The module design means it's intended to fit within your existing fuel tank setup, simplifying the installation process compared to some universal pumps. The included PTFE fuel lines are resistant to modern fuel blends and are built to last, ensuring reliable fuel delivery under pressure.

This kit is specifically for V8 4.8L, 5.3L, and 6.0L engines and excludes Flex Fuel models. It's a direct replacement for the fuel pump assembly in your truck, and while it's a more involved installation than a simple filter change, it doesn't require extensive fabrication. Make sure to check the specific fitment details for your truck model and year to ensure this is the right pump for your needs.
