Description
Walbro fuel pumps are trusted by enthusiasts, tuners, and professional builders for their proven reliability, consistent fuel delivery, and performance under demanding conditions. Whether you're replacing a worn factory pump or upgrading to support additional horsepower, Walbro offers fuel pumps engineered to provide the flow your engine needs.
Understanding Fuel Pump Flow (LPH)
Fuel pump capacity is measured in liters per hour (LPH), which indicates how much fuel the pump can deliver.
190 LPH – Excellent for stock engines and lightly modified vehicles. Ideal for daily drivers and OE-style replacements.
255 LPH – A popular upgrade for naturally aspirated and mild forced-induction applications. Supports many street performance builds.
340–350 LPH – Designed for vehicles with larger injectors, increased boost, or ethanol-compatible fuel systems that require additional fuel volume.
450–525 LPH – Built for high-horsepower applications, including heavily modified turbocharged, supercharged, and E85-powered vehicles.
Choosing the Right Walbro Fuel Pump
The right fuel pump depends on your vehicle's horsepower goals, fuel type, and modifications. Stock and lightly modified vehicles typically perform well with a 190 or 255 LPH pump, while higher-powered builds often require a 340 LPH or larger pump to maintain proper fuel delivery under load.
With a reputation built on quality, durability, and performance, Walbro fuel pumps remain one of the most trusted choices for both factory replacements and performance upgrades.
Note: Fuel pump requirements vary by application. Always verify fuel system capacity and compatibility before selecting a pump.
