This fuel pump is an excellent upgrade option for enthusiasts looking to improve their vehicle's fuel system efficiency and reliability.

The DW420 fuel pump boasts a robust 420 LPH (Liters Per Hour) flow rate, which is significantly higher than the stock fuel pump. This increased flow rate ensures that the engine receives an ample fuel supply during high-demand situations such as aggressive driving or when towing heavy loads.

Constructed from high-quality materials, this fuel pump features a heavy-duty cast aluminum housing and a billet steel drive shaft. The housing is anodized for added durability and corrosion resistance, while the drive shaft is hard-coated for superior strength and resistance to wear and tear. The pump's internal components, such as the impeller and volute, are made from high-strength materials to ensure longevity.

The DW420 fuel pump's design also includes a unique, patented "no-drip" fuel outlet, which virtually eliminates the possibility of fuel leaks. This feature is especially beneficial for those performing track days or autocross events, as the last thing you want is a fuel leak causing you to lose valuable time and precious track position.

Installing the Deatschwerks DW420 fuel pump is a straightforward process, as it is a direct replacement for the stock fuel pump. No modifications to the fuel tank or wiring harness are required, making it an ideal choice for those who want to upgrade their fuel system without the need for extensive modification.

In summary, the Deatschwerks DW420 420LPH In-Tank Fuel Pump (Part Number: 9-421-0846) is an excellent upgrade for Honda Integras and Civics looking to improve their fuel system's efficiency, reliability, and power delivery. With its high flow rate, robust construction, and easy installation, this fuel pump is a must-have for any enthusiast seeking to maximize their vehicle's performance.
