dumb question
What is the little pump that is located on the passenger side inner fender towards the back behind the battery? It makes a little vibrating noise when you turn the key on and it will do this while the truck is running as well. It will run for a little while then stop, it also has a small hose that runs across to the driver side under the fuse box somewhere. Is that noise something to worry about? I've had the truck for a few months and I've noticed it but I figured I better ask somebody.
