dude to much tv. i was just wondering how to do it with a carb?

You can't use propane in a carb. Carbs have floats in them that "meter" or control the amount of fuel that is in them. These floats are sitting in LIQUID gasoline all the time. Liquid propane is extremely cold and needs to be compressed in order to be liquid (i think). It can run on a fuel injection system because of the high pressure (30-35psi) that they run at. Most carbs (weber,dellorto,holley) use about 1.8-10 psi of fuel pressure, the propane will "vapor lock" the carb and push the float bowl all the way up on its needle and seat and shut fuel off.





stick with EFI, it costs more, but its worth it!

At first I thought you meant that you wanted to inject propane instead of water injection.

Ok it can be done. Sorry. but why?

i don't know maybe just for the hell of it or there may be some plusses about it or it could just be a waste of time you don't know until you try?

In some area of the country it is easier to get propane then gas, and the milage is supposed to be better, but drawbacks are that you gotta have those hefty *** tanks for the fuel..
