Zusammenfassung:	A method for detecting reverse flow for a dual fuel engine is disclosed. The engine may include an intake manifold, a liquid fuel supply line and a gaseous fuel supply line, the gaseous fuel supply line including a gaseous fuel supply and a gaseous fuel rail. The method may include: operating the dual fuel engine in a liquid fuel only mode via the liquid fuel supply line; determining a reverse flow in the gaseous fuel supply line; and outputting an indication of reverse flow in response to the determination of reverse flow.
