About our Conversion System

Working with fleets of all sizes, Donahue Gas and Alliance AutoGas are helping fleets save significantly on fuel costs and displace enormous amounts of gasoline.

The Prins VSI system uses five main components:

  • VSI Reducer: converts the liquid AutoGas to vapor

  • VSI Injector: injects the AutoGas into the manifold. (developed in cooperation with Honda Corp., Japan)

  • VSI Filter Units: filters particles out of the fuel.

  • VSI Computer: controls the VSI system.

  • LPG Switch: displays fuel level and allows driver control over fuel choice.

This system far surpasses previous models of conversion systems in performance and quality. Alliance AutoGas confidently asserts that the Prins system is the finest AutoGas Hybrid Vehicle conversion system available.

FORK LIFTS: If your business utilizes fork lifts, then you know how important propane can be to your production. To ensure you're not stuck without a forklift we offer several methods of fueling including on-site refills, tank exchanges and delivery.
