I am lookin around now...read a few DIY sites. Found a place in the UK that sells parts, shot off a few emails. I think I would have to relocate the battery to the trunk and install the vaporizer and other larger components in its place. Apparently you can install a mixer over the venturi's of the carb. Unfortunately I will need two of those for my setup.

I'd like to find someone who makes a rectangular LPG tank. Apparently the problem with cylindrical tanks on their sides are that the LPG gauge will show the fuel is being sucked down fast since its at the top of the bottle....then slow because its wider in the middle...then fast again as it nears the bottom of the cylinder. If they even make rectangular tanks...who knows..

From what I understand...its better for the engine to startup with gasoline and drive a few miles and when you are ready for the LPG to burn, you flip the switch, have it choke a little bit as the second system brings the fuel and continue on your way.
