DID YOU KNOW?

A simple add-on can help stop costly fuel spills.

Small Kit. Big Spill Protection.

GPRO vane pumps are already designed for quick Vacuum Breaker Kit installation.

This easy upgrade helps prevent unintended fuel siphoning, reducing the risk of fuel loss, cleanup costs, and environmental impact.

"Did You Know?"
A Simple Add‑On That Can Prevent Big Fuel Spills

Did you know that every GPRO® vane pump manufactured today already includes the predrilled ports needed to install a Vacuum Breaker Kit? That’s right, models like the V25, V20, and V35, along with legacy PRO20 and PRO35 fuel transfer pumps, are already designed with this safety feature in mind. The ports are built directly into the tank adapter and pump housing, making installation quick and easy.

What Is a Vacuum Breaker Kit?

A Vacuum Breaker Kit, sometimes called an anti‑siphon kit, is a simple but important safety accessory. Its job is to prevent unintended fuel siphoning when a pump isn’t running.

Here’s why that matters:

Even after a pump shuts off, fuel can continue flowing due to gravity or pressure in the system. A vacuum breaker stops that flow by breaking the siphon effect, helping protect your fuel, your equipment, and the environment.

“Don’t My Hose and Nozzle Already Prevent That?”

It’s a common assumption, and it’s partially true. A quality hose and nozzle can prevent siphoning under normal conditions. But real-world scenarios don’t always go as planned. Consider these situations:

  • A hose or nozzle accidentally gets run over
  • Someone forgets to remove the nozzle before driving away
  • A damaged hose creates a leak

Unfortunately, these things happen more often than you’d think, and when they do, fuel can siphon out of the tank fast.

So, What’s the Real Risk?

A small spill may not seem like a big deal, but the consequences can add up quickly:

  • Fuel loss: The cost of fuel from just one spill can exceed the price of a Vacuum Breaker Kit
  • Environmental impact: Fuel spills are environmental hazards
  • Cleanup costs and fines: These expenses can be significant, and in some cases, severe enough to threaten a small or midsized business

The Good News

Installing a Vacuum Breaker Kit is fast and easy, typically less than five minutes. Since GPRO vane pumps already have the required ports, there’s no guesswork or special modification needed.

Bottom line

A Vacuum Breaker Kit is a small, inexpensive upgrade that can help prevent major fuel loss, environmental issues, and unexpected costs. If your pump is already designed for it, adding one just makes sense.
