DeatschWerks X2 Surge Module with DW420 Pumps and Install Kit Nissan Skyline R33 / R34 1993-2002 | 9-421-7022
The DeatschWerks DW X2 Fuel Pump Module Kit (Part #9-421-7022) is a complete, high-flow dual-pump surge tank solution engineered specifically for the 1994–2002 Nissan Silvia (S14/S15) and Skyline (R33/R34). Designed for serious performance builds that demand reliable, high-volume fuel delivery, this kit pairs twin DW420 in-tank pumps with a purpose-built surge module to eliminate fuel starvation under hard cornering, aggressive acceleration, and high-boost conditions. Whether you're running a high-horsepower SR20DET or RB26DETT build, the DW X2 Module Kit is the definitive fuel system upgrade for track, drift, and street performance. Key Features & Benefits Dual DW420 Pump Configuration — Twin 420 lph (liters per hour) pumps work in tandem to deliver massive, uninterrupted fuel flow capable of supporting well over 1,000 WHP on E85 or pump gas builds. X2 Surge Module Design — Integrated surge/swirl pot reservoir ensures a constant fuel supply to the pumps, virtually eliminating fuel starvation during hard cornering, high-G acceleration, or low-fuel conditions common in performance and motorsport driving. Direct-Fit Application — Engineered as a drop-in replacement for the factory fuel pump module on compatible Nissan Silvia and Skyline chassis — no cutting, fabricating, or custom fuel hanger required. Complete Install Kit Included — Every fitting, connector, and hardware piece needed for a clean, professional installation is included right in the box, saving time and eliminating guesswork. Dual-Pump Redundancy — Running two pumps provides a built-in safety margin; if one pump experiences an issue at the track, the second continues to supply fuel to protect your engine investment. High-Quality Construction — Built to DeatschWerks' exacting standards with corrosion-resistant materials fully compatible with gasoline, E85, and ethanol-blended fuels. Supports Extreme Power Levels — Ideal for turbocharged, supercharged, or nitrous-assisted builds pushing the limits of the factory fuel system, making it the best high-flow fuel pump kit for the S-chassis and GT-R platform.

Installation The DW X2 Fuel Pump Module Kit is designed as a direct drop-in replacement for the OEM fuel pump assembly, significantly reducing installation complexity compared to universal surge tank setups. The included hardware kit provides all necessary fittings and connectors for a complete installation. While this is a bolt-in application, DeatschWerks recommends installation by a qualified automotive technician or experienced performance shop familiar with fuel system modifications. Always follow proper fuel system safety procedures — depressurize the fuel system, work in a well-ventilated area, and disconnect the battery before beginning installation. Is this fuel pump kit compatible with E85? Yes — the DW420 pumps and all wetted components in the X2 module are fully compatible with E85 and ethanol-blended fuels, making this kit an excellent choice for flex-fuel and dedicated E85 performance builds.
