What is this and how do I fix it?
I am hoping someone can point me in the right direction. While replacing the spark plugs, I came across a piece of rubber cracked and has holes. As you can see, I put some electrical tape on it, but I am not sure if this is a vacuum line or part of the emissions system. Either way, the kid at Napa said he didn't list any part to fix it and suggested I go to Ford. If you know, could you tell me what this is and how I should go about correcting the issue? Thank you in advance!
