Deatschwerks Fuel Pump Hardwire Kit

Universal Fitment – Fits Most Models

FPHWK

Overview:

The Deatschwerks Fuel Pump Hardwire Kit is designed to maximize the performance of your DW301 or other high flow fuel pumps by ensuring they receive the proper voltage needed for optimal operation. Over time, original equipment (OE) wiring can degrade or become compromised, limiting the voltage supplied to your fuel pump and potentially restricting fuel delivery under demanding conditions.

This hardwire kit provides a direct, reliable connection from your vehicle’s battery to your fuel pump, eliminating voltage drop caused by aging or inadequate wiring. It is an essential upgrade for vehicles over 10 years old, cars producing over 400 wheel horsepower, or any vehicle that was not originally engineered to support high horsepower applications. With this kit, you can confidently push your fuel pump to its limits without worrying about electrical constraints.

Key Features:

This kit includes everything needed for a safe and effective hardwire installation, ensuring consistent fuel pump performance and reliability.

• Ensures your high flow fuel pump receives sufficient voltage for peak performance
• Direct battery connection eliminates voltage drop from old or compromised OE wiring
• Includes high-quality 12-gauge SLX specification power and ground cables for durability and electrical efficiency
• 30 amp in-line fuse protects the circuit from electrical faults
• 40 amp automotive relay and 4-lead relay socket with pigtails provide reliable switching and easy installation
• Comprehensive installation instructions guide you through a straightforward wiring process
• Includes a Deatschwerks window decal for enthusiasts
• Universal application fits most vehicles, making it a versatile upgrade option

Construction & Design:

The kit features premium 12-gauge SLX specification wiring designed to handle high current loads safely and efficiently. The red power cable and black ground cable are engineered for durability and resistance to heat and abrasion, ensuring long-lasting performance in the engine bay environment.

The included 40 amp automotive relay and 30 amp in-line fuse provide essential circuit protection and reliable switching, reducing the risk of electrical issues. The relay socket with pigtails simplifies wiring connections, making installation accessible even for those with moderate automotive electrical experience.

Installation & Fitment:

The Deatschwerks Fuel Pump Hardwire Kit is designed for universal fitment, compatible with most vehicles equipped with high flow fuel pumps such as the DW301. It is especially recommended for cars over 10 years old, vehicles making over 400 wheel horsepower, and those not originally designed for high horsepower applications.

Installation involves wiring the fuel pump directly to the battery through the supplied relay and fuse, bypassing the factory wiring harness to ensure consistent voltage delivery. The kit includes detailed instructions to guide you through the process safely and efficiently.

No special modifications to your vehicle’s wiring harness are required beyond the installation steps outlined, making this a practical upgrade for enhanced fuel system reliability.

What's Included:

• 15 feet of 12-gauge SLX specification red power cable
• 5 feet of 12-gauge SLX specification black ground cable
• 30 amp in-line fuse for circuit protection
• 40 amp automotive relay for reliable switching
• 4-lead relay socket with pigtails for easy wiring connections
• Comprehensive installation instructions
• Deatschwerks window decal

Ideal For:

This hardwire kit is ideal for performance enthusiasts and daily drivers alike who want to ensure their high flow fuel pump operates at full capacity without electrical limitations. It is particularly beneficial for:

• Vehicles over 10 years old with aging factory wiring
• Cars producing more than 400 wheel horsepower
• Vehicles originally not designed to support high horsepower upgrades
