Part Description:

One of the most popular fuel pump brands on the market, and a top seller here at H-Tune. Walbro offer a vast catalog of fuel pumps for models worldwide. We've split them into two flow ratings, and two different types which covers 99% of applications we're asked about here.

Our most popular pump type by far is "255lph High Pressure" suitable for almost all applications.

Flow Rating:

The below figures are given as very loose guidelines, the amount of horsepower a pump will support depends on a huge variety of factors, from the injectors used, to engine efficiency and the aspiration. For more precise figures for your application, use a fuel pump calculator found with a quick Google search.

  • 190lph: 300-400hp Max
  • 255lph: 500-600hp Max

Standard vs. High Pressure

Standard fuel pumps are generally stock replacements. Installing a Walbro high pressure fuel pump in a non-performance vehicle will not damage your motor. All fuel first passes through fuel injectors and a fuel pressure regulator which only send the required amount of fuel into the intake manifold, sending the unused fuel (usually more than 1000%) back to the fuel tank.

Walbro performance fuel systems are designed to deliver the speed, power, torque and reliability you expect. That's why 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.
