name that part

Hello. I have been hearing a clicking noise near the back of my car lately. The noise is a series of 3 clicks in a row, and there is not anything I can do to reproduce it on demand. I was making sure that my fuel filler tube was not leaking last night and I noticed a part right near the fuel filler neck that has a relatively large diameter (maybe 5/8 inch or bigger) hose and an electrical connector going to it. If anyone knows what it might be, please let me know. If I need to, I can post a pic. Thanks!

thinking we might need a pic on this one......

Maybe the vapor canister? It's located at the rear driver side fender; I just don't remember having an electrical connector on it but does have a couple of hoses with a bigger diameter.

The only thing I can think of is the evaporative emissions vent solenoid.

That's got to be it. Just a large diameter hose and an electrical connector going to a small box with vents in the side. Thanks Bob! How is it supposed to work though? Every so often I hear it click three times in a row, like it's trying to energize or something. I'm not getting an SES light or anything, I've just been noticing it lately and wondering if it is supposed to do that.

Yes it is supposed to do that.
