Natural Gas Conversion?
very high compression, even propane wants something
north of 12:1. And evidently filling is a real problem in
most places, unless you have natural gas plumbed in
your house and want to throw down $ for the high
pressure pump you'll need for filling the cylinder. Which
is pretty large for the amount of energy it holds, and
that's why only city busses and short-route delivery
vans and city vehicles use it today.
