Walbro Fuel Pump Module Assembly

Walbro Fuel Pump Module Assemblies: OE Pedigree Meets High-Performance Engineering

When an engine demands consistent, high-pressure fuel delivery — whether it's a stock daily driver or a modified powerplant pushing well past 500 horsepower — the fuel pump module assembly is the unsung hero keeping everything running. Walbro has spent over six decades earning its place as one of the most trusted names in fuel system technology, and its Fuel Pump Module Assemblies are a direct reflection of that heritage.

A Legacy Built on Fuel System Expertise

Walbro was founded in 1950 in Fenton, Michigan, and initially specialized in small-engine carburetors before expanding aggressively into automotive fuel systems. Walbro added an electronics division in 1993, developing electronic fuel injection technology — with early success in fuel modules for the Chrysler Cirrus ultimately leading to Walbro becoming the supplier of fuel modules for Chrysler's minivan series. That OEM-level experience forms the backbone of every module assembly the brand produces today.

What Sets Walbro Fuel Pump Module Assemblies Apart

Walbro's complete drop-in module assemblies integrate a high-performance fuel pump with filtration, level-sensing, and storage — featuring OE-like fit similar to a traditional replacement module but with high-performance flow. This "drop-in" philosophy is central to the Walbro design approach: Walbro's high-performance fuel pump systems are complete assemblies including the fuel pump module and wiring that plug directly into the factory harness. That means no splicing, no adapter kits, and no guesswork — just a clean, reliable installation.

These Walbro fuel pump assemblies are fully capable of supporting in excess of 600 rear wheel horsepower with no modifications needed to install and hook up into the factory fuel tank and fuel line system. For enthusiasts running forced induction, high-compression builds, or alternative fuels, this level of capability in a factory-style package is genuinely hard to find.

High-Flow Technology and Flex-Fuel Compatibility

Walbro high-performance fuel pumps and modules are developed and built specifically to meet the demands of today's high-pressure and high-flow engines with efficient and durable performance. Walbro's lineup includes a wide range of high-performance fuel modules built to OE specifications and featuring vehicle-specific high-performance pumps. Modules are engineered to work with both standard gasoline and E85 ethanol blends, making them a practical upgrade path for flex-fuel applications.

As a brand of TI Automotive, Walbro has the backing of a global manufacturing and testing network — a Tier-1 supplier that provides fluid storage, delivery, and carrying technology to nearly 70 percent of the world's vehicles. That industrial-scale engineering capability filters directly into every module assembly Walbro offers to the performance aftermarket.
