Fuel Pump Assy - 255lph Gas - Mustang 1999-00

The Walbro TU228HP-4 Fuel Pump Assembly is a 255 lph electric in-tank fuel pump designed specifically for Ford Mustang 1999–2000 models equipped with gasoline engines. This OEM-specification replacement pump features a factory outlet and return configuration with an integrated sending unit, making it a direct-fit solution for fuel system restoration and high-performance upgrades on late-1990s Mustang platforms.

The 255 lph flow rate delivers adequate fuel pressure and volume for stock and mildly modified fuel-injected Mustang engines, ensuring consistent atomization and combustion across the RPM range. Walbro and TI Automotive fuel systems are industry-standard suppliers for OEM and aftermarket automotive fuel delivery, known for precision engineering and long service life in demanding automotive environments. The in-tank design integrates the pump directly into the fuel tank assembly, reducing external plumbing and maintaining factory-correct fuel system architecture. The included sending unit allows for accurate fuel level gauge operation on the instrument cluster.

This fuel pump assembly is essential for Mustang owners performing fuel tank service, addressing weak fuel pressure symptoms, or replacing a failing pump that compromises starting, idle stability, or wide-open-throttle performance. It is compatible with 1999–2000 Mustang models across all engine displacements and is suitable for both street and track applications where reliable fuel delivery is non-negotiable. Proper installation requires fuel system depressurization and careful handling of the pump module during tank work.
