Walbro – The Fuel Pump that Feeds Your Power
In the world of tuning, there is one simple truth: more air requires more fuel. You can install the biggest turbo, the best intake, and the freest-flowing exhaust, but if your fuel pump can't keep up, it's all for nothing. And when it comes to reliable, high-performance fuel delivery, professionals have had one answer for decades—Walbro. It's not just a brand. It's the industry standard.
This is the "unseen hero" under the hood of thousands of the world's most powerful cars. This is American engineering that has become synonymous with reliability. At ATOMIC-SHOP, as an official distributor, we offer genuine Walbro / TI Automotive pumps, so your engine never goes hungry.

The trust in Walbro isn't marketing; it's the #1 choice for any project, from Stage 1 to 1000+ hp.
- Made in the USA: Every genuine Walbro pump is manufactured in the USA, which is a guarantee of the highest quality and adherence to stated specifications.

Key Walbro Models: The Science of Flow
Walbro's advantage lies in its wide range of pumps for any task, from mild tuning to extreme projects.
| Model | Flow Rate (LPH) | E85 Compatible | Application |
|---|---|---|---|
| Walbro 255 (GSS342) | 255 | No | The classic. Ideal for projects up to 450-500 hp on gasoline. |
| Walbro 450 (F90000267) | 450 | Yes | The "golden mean." For projects from 500-750 hp on gasoline or up to 550 hp on E85. |
| Walbro 525 "Hellcat" (F90000285) | 525 | Yes | The choice for extreme power. 700-1000+ hp on gasoline or up to 750 hp on E85. |
Recommendations for Real-World Conditions
Tuning with ethanol (E85) is becoming increasingly popular. This places special demands on the fuel system.
- For E85 Projects: It is mandatory to choose pumps that are compatible with ethanol, such as the Walbro 450 or Walbro 525. They have special internal components resistant to the aggressive effects of alcohol. Using a standard pump (like the Walbro 255) with E85 will lead to its rapid failure.
- For Any Tune: Upgrading the fuel pump is one of the first and most important modifications when increasing power. It is your insurance against a lean condition and potential engine destruction.
Frequently Asked Questions (FAQ)
Why can't I just buy a cheap Chinese knock-off pump?
The fuel pump is the heart of your engine. Cheap knock-offs often fail to deliver their advertised flow rates, overheat, and can fail at any moment. A sudden pump failure under load leads to a lean air-fuel mixture, detonation, and consequently, engine destruction. The cost of repairs will be hundreds of times higher than the savings on the pump.
What does "LPH" mean?
It stands for "Liters Per Hour." This metric shows how much fuel the pump can deliver per hour at a specific pressure. The higher the engine's power, the greater the pump's flow rate needs to be.
Do I need to upgrade the wiring when installing a high-flow pump?
Yes, this is highly recommended. High-flow pumps (450 LPH and above) draw significantly more current than standard ones. The factory wiring may not handle the load, leading to a voltage drop, reduced pump performance, or even a fire. Using an upgraded relay and wiring is mandatory for safety and efficiency.
How can I distinguish a genuine Walbro pump from a fake?
The market is flooded with counterfeit Walbro pumps. A genuine pump has clear markings, the TI Automotive logo, and unique design features. Fakes often have poor casting quality and markings. The best way to protect yourself is to buy products only from official distributors, such as ATOMIC-SHOP.
