Fuel Pump Assy - 255lph Gas - Mustang 2001-04

The Walbro TU229HP-4 Fuel Pump Assembly—255 lph Gas for Ford Mustang (2001–2004) is purpose-built for serious enthusiasts upgrading their naturally aspirated or supercharged New Edge platform. This high-flow fuel pump assembly replaces the stock unit when modifications demand increased fuel delivery capacity, whether you're tuning for performance, installing larger injectors, or pushing beyond factory horsepower limits. The 255-liter-per-hour (lph) flow rate makes it the go-to choice for turbocharged and forced-induction builds on this generation, providing the fuel volume needed to support reliable combustion across the RPM band.

Walbro and TI Automotive engineered this fuel pump assembly with proven reliability in high-demand racing and street applications. The internal impeller design delivers consistent pressure and flow even under sustained boost or high RPM operation, critical for maintaining correct air-fuel ratios during acceleration and top-end pulls. This assembly integrates the pump motor, fuel strainer, check valve, and regulator into a complete drop-in unit that fits the Mustang fuel tank, eliminating the need for external regulators or complex plumbing modifications on most bolt-on setups.

Owners of modified 2001–2004 Mustangs—whether running blower kits, turbo conversions, or mild street builds—benefit from this pump's reputation for longevity and stable pressure output. Installation requires fuel tank removal and standard hand tools; no special equipment needed. The assembly is a direct replacement for the factory pump, making it an ideal upgrade during tank service or when transitioning to performance fuel maps that demand higher volume delivery than OEM specifications allow.
