Propane is a by-product of the refining process of natural gas and crude oil. About 3% of a barrel of oil becomes propane. Propane boils at -44 degrees Fahrenheit; when it is vaporized, it becomes a gas again. Because it vaporizes at such a low temperature, it mixes easily with air. Therefore, it doesn't require a high temperature (over 400 degrees Fahrenheit for gasoline) for it to atomize. This improves cold starts, emissions, and driveability. Propane is a stable fuel; it doesn't go bad if you don't use it!
Since propane has such a low carbon content, motor oil never gets dirty which increases engine life. The oil does still need to be changed, though not as often. Spark plug life is dramatically extended. Also, you cannot "flood" a propane engine. When a gasoline engine "floods," raw fuel enters the cylinders, washing past the rings and into the oil, also wetting the plugs. Propane carburetion automatically compensates for altitude changes, saving carb re-jetting and computer re-learn.
Since propane is under pressure, there are no fuel pumps, no float bowl, or needle and seat. Another plus is the high octane rating of propane between 100 and 110. This means that if you are turbocharging or supercharging, it is the ideal fuel.

Prolongs engine life
Is affordable
No wiring except the on/off solenoid.
Propane is not harmful to soil or water
This is the most reliable fuel system on the market, and all of our kits are made in the good ole U.S.A.!
