525 LPH Fuel Pump Module 83-97 Ford Mustang

The Holley 525 LPH Fuel Pump Module for 83-97 Ford Mustang is a direct-replacement electric fuel pump assembly engineered to support high-performance and modified engine builds. Rated at 525 liters per hour (LPH), this module delivers consistent fuel pressure to support naturally aspirated stroker builds, supercharged applications, and turbocharged Mustang platforms without requiring custom fuel system fabrication.

At 525 LPH, this pump provides the flow capacity needed for engine modifications that demand higher fuel volume than OEM systems supply. The module includes the complete installation kit, eliminating the need for separate tank access or complex plumbing modifications. The assembly is designed as a plug-compatible upgrade for 1983 through 1997 Mustang fuel tanks, preserving stock mounting and electrical integration while substantially increasing available fuel delivery. The compact dimensions (4.4 x 4.3 x 14.6 inches) and 2.2-pound weight ensure straightforward installation within the factory tank cavity.

This module is ideal for Mustang enthusiasts pursuing power upgrades—from mild cam and head work to significant displacement increases or forced induction. Owners upgrading carbureted or stock fuel-injected systems to support 400+ horsepower naturally find this pump eliminates fuel starvation issues at sustained high RPM. The kit-based design reduces labor time and technical complexity compared to traditional in-tank pump swaps, making it accessible to both shop installations and experienced DIY builders.

The Holley Sniper fuel pump line represents proven electric fuel delivery for street and performance applications. This 525 LPH capacity positions the module between mild street upgrades and extreme racing systems, covering the majority of Second-Generation Mustang performance modifications.
