Whilst trying to work on the driver side rear suspension as documented elsewhere, I noticed for the first time a small rubber hose in the vicinity of the gas tank. The end was free as if it once attached somewhere. The only thing I could think of was a drain hose for the trunk but I don't recall seeing an outlet there the last time I had the spare out. Any idea what this could be? In another matter, I switched the wiper arms. Who knew?
