AFAIK, that's a worst-case for after-market conversions with poor
airflow. Best-case is about a 4% loss, and real-world typically ends up
being somewhere between the two (but I think CNG usually reduces
efficiency more than LPG does).

No, that large drop is from the lower amount of BTUs put out by the
other fuels in comparison to gasoline. Gas has noticeably more power.
Propane puts out 74% as much energy as gasoline, diesel more than gas.

Oh, whoever posted that other link yesterday to kits for conversion
should know that the website is dead and their 800 phone is off.

Does anyone have a list of sites that DO have NG conversions that
allow NG/LP/gas conversions?

If you're referring to the propane-generators.com web site, it is now
on line with a note, "We apologize for the inconvenience during this
website update." I haven't tried their 800 number.
