I've driven propane taxis, and have a propane endorsment on my mechanics 
licence propane is a good fuel -> almost instant heat in the winter much 
cleaner fuel. I haven't seen liquid injection though, good idea.

you may have problems with refueling stations ( I once had to leave a 
truck in Georgia because none of the propane companies beleive a truck 
would run on propane ( they didn't beleive that the adaptor was for 
propane 8((
