How can I convert my F 150 to propane?

well since you have an f150 it is a gas engine so your best bet would be to check with your local propane distributor. their trucks run on propane and they can tell your where to get the conversion done. it is not really a do-it-yourself job if you want it done right. a friend had is snap-on tool truck converted because the mpg is the same and the cost per gallon is half the price of gas!!!!!!!!!!!!!
