EFI Done Right.

Electric Fuel Injection Technology by Vanguard

We believe that true innovation comes from the proper application of technology.

We designed our Vanguard EFI systems to prioritize the benefits of EFI to maximize the specific category productivity targets.

For instance, our Vanguard EFI solution for the air-cooled marine market prioritizes increased power and direct throttle response, while our EFI offerings for commercial cutters place a heavy emphasis on fuel economy and improved load governance.

Tailored EFI Solutions For:

  • Light Construction
  • Power generation
  • Fire & Rescue
  • Commercial Turf
  • Air-Cooled Marine


  • Reduces Total Cost of Ownership
    Improved fuel economy up to 25% depending on the application and load. Provides improved stale fuel resistance resulting in reducing unnecessary servicing.
  • Increases Productivity
    Improves the overall performance of the equipment ensuring a smoother acceptance as more load is applied. With increased horsepower it ultimately delivers more useable power.
    EFI enhances altitude compensation resulting in less power loss when used at higher altitudes. All these benefits result in increased equipment productivity.
  • Provides Easier more Reliable Starting
    Provides a more direct, choke-less starting experience
