After proper installation, if the engine stalls, the fuel will STOP FLOWING between the Regulator and the adapter. Some engine applications (we are unable to determine which makes/models) might have a disturbance in performance when running your unit on gasoline. If this occurs you can remove the adapter temporarily when using gasoline. This will not hurt your engine. We will not be issuing refunds for this reason.
