taken from their website:
22RE kits.
We now have a kit designed to use the E.F.I. engine. They are designed to run propane only. Lose that smashed up gas tank and poor driveability due to faulty sensors and old wiring with bad connections. It requires a carbureted distributor and ignition coil. It retains the stock intake manifold and throttle cables. It is designed to remove all of the efi wiring and sensors related to gasoline, resulting in two wires reqiured to power the engine!
