Plastic air tube

It is probably a vacuum line, but can you get a picture of it and we will be sure we are talking about the same line. Plus we may be able to identify it just by sight. Thanks

Good afternoon,

Do you mean from the valve cover to the rubber line from the air filter to the throttle body?

It is a tube for taking crankcase pressure and sending it back into the intake manifold for reburning.
