I'm no expert but I bet you can just re-install the gasoline components ie throttle body etc. In your case the vehicle came with an ECM to control the fuel ratio, so of you are still running LP with an ecm it must have a custom MEMCAL installed along with a regulator etc.

In any even those LP conversion parts are worth a few dollars to someone looking for them. You might be able to at least do some even swapping to get your vehicle back to gasoline.

Here is a site that discusses small engines that run on both LP and gasoline.

Here is a site discussing a propane via TBI conversion (ie dual fuel):

Really would like to hear how you make out, do you have a local LP dealer that you can stop by and check with?

PLEASE keep us posted.
