Review DEATSCHWERKS Premium Electric In tank Fuel Pump Honda fits CIVIC DW400 SI 2006–2011

Introducing the Deatschwerks DW400 Electric In-Tank Fuel Pump (Part Number: 9-401-7041) specifically designed for the Honda Civic SI models from 2006 to 2011. This high-performance fuel pump is an excellent upgrade for those looking to improve their vehicle's fuel system.

The DW400 fuel pump is an in-tank electric design, meaning it is installed inside the fuel tank and draws power directly from the vehicle's electrical system. This design eliminates the need for a fuel pump relay or an external fuel pump, making installation simpler and more straightforward.

This Deatschwerks fuel pump boasts several key features that set it apart from OEM pumps. It is constructed of high-quality materials, including a billet aluminum housing, stainless steel impeller, and a ceramic shaft. These materials ensure the pump can handle increased fuel flow rates and the rigors of high-performance driving.

The DW400 is capable of delivering up to 350LPH (92 gallons per hour) of fuel flow, which is a significant increase over the stock fuel pump's capacity. This increased fuel flow translates to better engine response, smoother idling, and more consistent power delivery, especially during high-load situations.

Additionally, the DW400 fuel pump comes with a built-in voltage regulator, which maintains a consistent voltage level to the pump, ensuring optimal performance and longevity. The regulator also features a thermal overload protection system, which shuts the pump off if it gets too hot to prevent damage.

Installation of the DW400 fuel pump is relatively straightforward. It comes with all necessary hardware, including fuel lines and a fuel filter, to make the process as hassle-free as possible. However, it's essential to note that the installation process may require some modifications to the fuel tank and fuel lines, depending on the specific Honda Civic SI model.

In conclusion, the Deatschwerks DW400 Electric In-Tank Fuel Pump (Part Number: 9-401-7041) is an excellent upgrade for 2006-2011 Honda Civic SI owners looking to enhance their vehicle's fuel system. With its high-quality construction, increased fuel flow capacity, built-in voltage regulator, and thermal overload protection, this fuel pump is designed to deliver consistent, reliable performance and improved engine response.
