Walbro High-Flow Fuel Pumps

Walbro fuel pumps support fuel delivery upgrades for naturally aspirated, turbocharged, supercharged, drag, street, and high-output EFI builds. Choose pump flow based on horsepower, fuel type, fuel pressure, voltage, and the complete fuel system design.

Walbro 255 LPH Fuel Pumps

Walbro 255 LPH pumps are common in-tank upgrades for selected gasoline performance applications. Confirm pressure requirements, inlet and outlet design, electrical connector, pump dimensions, and fuel module compatibility before ordering.

Walbro 400, 450, 535, and 550 LPH Pumps

Higher-flow Walbro pumps support increased fuel demand on selected performance and ethanol-fueled builds. Larger pumps may require upgraded wiring, relays, fuses, filters, fuel lines, injectors, rails, regulators, and ECU calibration.

• Match pump flow to horsepower, fuel type, and fuel pressure.
• Verify gasoline, E85, or other fuel compatibility.
• Check pump dimensions, inlet, outlet, connector, and mounting style.
• Determine whether the vehicle uses a return or returnless system.
• Confirm fuel tank module and pump assembly compatibility.
• Check wiring, relay, fuse, controller, and voltage requirements.
• Match filters, fuel lines, injectors, rails, and regulators to the pump.
• Replace worn seals, filter socks, hoses, and tank hardware when required.
• Verify fuel pressure and inspect for leaks after installation.

Frequently Asked Questions About Walbro

What is a Walbro 255 fuel pump used for?

A Walbro 255 LPH pump is commonly used as a high-flow in-tank upgrade for selected gasoline, naturally aspirated, turbocharged, and supercharged EFI applications.

Do larger Walbro pumps require wiring upgrades?

They can. Higher-flow pumps may draw more current, so verify voltage under load and use properly sized wiring, relays, fuses, connectors, and grounds.

Can a Walbro pump run E85?

Fuel compatibility depends on the exact pump and part number. Confirm E85 approval and ensure the complete fuel system is compatible with ethanol.

Will a universal Walbro pump fit a factory fuel module?

Not always. Compare pump dimensions, connector type, filter sock, mounting hardware, inlet and outlet design, and fuel module configuration before ordering.

Do I need larger injectors with a higher-flow pump?

A larger pump does not automatically require larger injectors. Injector size and calibration must match the intended horsepower, fuel type, pressure, and engine setup.

What is the difference between an in-tank and inline fuel pump?

An in-tank pump mounts inside the fuel tank or fuel module. An inline pump mounts in the fuel line outside the tank. Choose the design that matches the vehicle and fuel system layout.

How do I choose the correct pump flow rate?

Consider horsepower, fuel type, base fuel pressure, boost pressure, voltage, duty cycle, and the pump’s flow curve. Do not select a pump by LPH rating alone.

Do Walbro fuel pump kits include wiring and filters?

Included components vary by product. Review the listing to confirm whether wiring, filters, hose, installation hardware, and instructions are included.

Can Walbro pumps be used in engine swap builds?

Yes. Universal pumps and installation kits can support selected engine swaps and custom builds when pump dimensions, wiring, fuel pressure, and mounting requirements are properly matched.

Should Walbro fuel pumps be professionally installed?

Professional installation is recommended for fuel tank removal, custom wiring, pump module modification, pressure testing, E85 conversions, and high-output fuel system work.
