Engine Area Ventilation Blower

[kulle]

Does anyone know what the vent tubing, that resembles a dryer vent is called that connects up to the blower to vent gas fumes - and where to get a replacement or alternative options? I noticed mine is torn and seems brittle...is that a 4"-6" diameter or i guess that varies? Its on a 1993 4.3 Merc if that even matters.

Thanks all

Most is 3 inch but also comes in 4 inch and sold in 10 and 50 ft lengths. Doesn't cost that much, I bought a 50 ft box and used about 10 ft.
