An engine intake manifold has ribs (18) extending along the internal walls (16) of the manifold passages (12) leading from the riser block (10) to the engine cylinders. Liquid fuel which is present in the manifold passages (12) is blown along the passages (12) by the flowing vapour which flows across the ribs (18), and is blown off the tops of the ribs to become vapourised before it reaches the engine. |
