Overview
DeatschWerks DW430C X3 Series Fuel Pump Modules
DeatschWerks DW430C X3 Series fuel pump modules are high performance fuel delivery systems designed to support extreme horsepower (900+ hp on gas, 700+ hp on E85) by integrating up to three compact pumps into a single, E85-compatible drop-in unit. These modules feature billet construction, a fuel-cooling bucket, and PTFE plumbing to ensure high flow, reliability, and reduced noise.
Key details:
* High flow and power: The DW430C itself pumps flow over 430 liters per hour (LPH) at 40 psi, designed for high-pressure performance (383 lph at 60 psi)
* X3 module design: Specifically designed for maximum performance, the X3 modules often utilize triple-pump configurations to deliver superior fuel volume, ideal for race-only or high-demand boosted applications
* Compact 38mm design: The DW430C uses a 38mm form factor, fitting into restricted factory modules better than larger, traditional 39mm high-flow pumps
* E85 compatibility: Engineered with advanced carbon matrix commutators and durable components, making them fully compatible with E85 and other ethanol blends
* Vehicle-specific fitment: Available for popular, high performance vehicles, including the 1998-2004 Ford Mustang and 2009-24 Nissan R35 GTR
* Integration: Features billet top hats, -10 AN feed, and -8 AN return ports, with a factory-style bucket to maintain consistent fuel levels during cornering
* These systems are typically used for high-horsepower builds requiring a significant, reliable upgrade over stock fuel systems. They often require a return-style fuel system and should not be used with stock return-less setups
