If you’re building a high-horsepower Pontiac G8, your fuel system needs to be able to keep up. The DeatschWerks X2 Dual DW300 Fuel Pump Module provides the fuel volume and reliability needed to support serious power while retaining the drivability and functionality of an OEM-style fuel system.

Built around the proven 5th Gen Camaro fuel module architecture, this system has become one of the most popular fuel pump upgrades for the Pontiac G8. To make installation simple, every kit includes the necessary G8-specific adapters, allowing the module to integrate cleanly into your vehicle while retaining factory fuel tank functionality.

At the heart of the module are dual DeatschWerks DW300 fuel pumps, delivering an impressive 560 liters per hour at 58 PSI—over 140% more flow than the factory Camaro ZL1 fuel module. This provides ample fuel capacity for naturally aspirated, supercharged, turbocharged, and E85-powered combinations well beyond the limitations of the factory system.

Unlike many aftermarket fuel solutions that require extensive tank modifications or eliminate factory features, the X2 module maintains everything enthusiasts appreciate about the OEM design. The factory surge bucket, fuel level sensor, and full fuel tank capacity are all retained, ensuring excellent fuel control during hard acceleration while preserving everyday drivability.

The module also features high-flow -8AN feed and -6AN return ports, making it the perfect foundation for custom return-style fuel systems and high-performance fuel plumbing. Whether you’re installing larger injectors, upgrading to E85, or planning future power increases, the X2 module provides the fuel delivery capability to support your build.

Each module arrives fully assembled from DeatschWerks, eliminating the guesswork of piecing together a multi-pump system. Simply install the module, complete your plumbing, and finish the electrical system to create a clean, reliable fuel system built for serious performance.

For best results, professional installation is strongly recommended. Because the module utilizes dual high-output fuel pumps, proper electrical upgrades—including a relay system and 12-gauge hardwire kit—are required to ensure maximum voltage and consistent pump performance.

If you’re looking for an OEM-quality solution that combines factory reliability with the fuel capacity required for today’s high-performance builds, the DeatschWerks X2 Fuel Pump Module is one of the best upgrades you can make.

Why Choose the DeatschWerks X2?

There are plenty of aftermarket fuel system options available—but very few combine OEM fitment, factory functionality, and serious fuel capacity like the X2.

Instead of replacing your entire fuel tank or fabricating a custom solution, the X2 retains the features that make the factory system work so well while dramatically increasing fuel flow. The result is an OEM-style module capable of supporting today’s high-horsepower street and race cars without compromising reliability.

Whether your goal is 700 HP or 1,200+ HP, the DeatschWerks X2 gives your G8 the fuel system foundation needed to grow with your build. I think you’ll appreciate the confidence that comes from knowing your fuel system is no longer the limiting factor.
