I recently read an article in an offroad magazine to convert gasoline engines to propane. I was wondering if anyone would have any clue about where to find more info on this subject. I've found a rather dated Do It yourself guide here. Anyhow, as Hank Hill has taught us, propane is a clean gas, its plentiful, and alot cheaper. I've got an old Datsun pickup with a 2.2l 4 cylinder. I thought this would be a perfect candidate for a propane conversion. There is plenty of room under the hood, and plenty of room in the bed for tanks and such. It seems all that is needed is a different carb. I would also like to find out if it would be possible to convert a fuel injected vehicle to run of propane. Any information would be appreciated. So far I've noticed Impco seems to sell do it yourself kits, I was just wondering if others thought this a reasonable waste of time?
