Converting to propane power

September 1, 2011 | By Richard Prince


I am considering converting one of my vehicles to propane but I cannot find any information on how to do it.

Are there kits available? Is it possible to convert “antique” vehicles to run on propane? By antique I am talking about cars made from the 1940s to the 1970s. There are TV commercials about how much it would benefit the planet, but I can’t seem to find anything about the availability of the parts necessary to do the conversion. Have you had an article about the conversion in your magazine? If so, I don’t remember it.


It is possible to convert just about any engine, old or new, to run on propane and in an odd twist of circumstances it’s actually easier to convert vintage vehicles from a legal perspective. This is because it’s contrary to a long list of federal laws and regulations, as well as various local laws and regulations, to replace or modify any components that are a part of a vehicle’s emissions control systems, so converting an emissions-era vehicle in a legal manner gets very complicated.

You are better off buying a complete kit with all or nearly all of the components needed. In general, this means a kit with valves, tank, actuators, fuel controller, electronics and software.

Some companies that sell propane conversion kits and individual parts, and that have a lot of information you’ll find of interest, include Impco Automotive (, ( and Raso Enterprises
