There are two basic ways doing a propane conversion: straight (dedicated) and dual fuel.
Straight propane systems are best suited to older non-computer controlled engines with a good supply of fuel or to off-road applications. A good example of an older straight propane conversion is the 1977 Pontiac conversion I did several years ago.
A dual fuel propane conversion is, for all intents and purposes, the only type that stands any chance of meeting North American emission regulations. With the computerized integration of fuel injection and ignition systems of modern engines, dual fuel propane conversions are far easier to do than straight propane conversions.
The information presented is not intended to be a do-it-yourself guide to propane conversions but rather as information to help you decide if propane is right for you. Do not attempt to undertake the conversion of any vehicle unless you have the training to do so because improper conversions can potentially cause serious injury and property damage.
As I am not in the business of doing propane conversion installations, the information presented in these articles may not be entirely correct. However, I have done my best to ensure that the information is accurate and would greatly appreciate suggestions, corrections, and any other advice for improvements. I would also really appreciate any visitors with propane conversions of their own to send me photos of their systems. I will try to feature as many cars as possible but I can't promise to feature every one I receive.
