Can anyone tell me

what this is and what it does. My 1996 Mazda B3000 started runing rough all of a sudden and while looking for things that might have caused it I found this. Both ends have rubber tubes connected to nozzles on both ends. The tubes were both worn and crumbley. Any ideas? Thanks.

My first guess is vacuum tubing. Where were the ends connected?

Thanks Sigo and Kahrnut. I was thinking EGR but wasn't sure. I appreciate the help.
