Hey guys. Sorry I don't currently have a pic. But my motor is the 318 v8 in the 91 d250. In the intake snorkel on the bottom of the piping about 7 inches before the carb. There is a black 2 inch hose that goes from the intake down to ??? It's not connected currently. Truck runs and idles fine. Any heads up what this is so I can order a replacement. Thanks. I'll get a pic up later. Sorry I'm new to this world. Never owned a dodge or older vehicle. Doing AL the work myself learning along the way.
