Fuel Line Oily/Greasy

I had a thick oily/greasy coating on the large fuel filler line. I cleaned it off and checked the hose clamp (wasn't very loose - one turn tightened it). What would cause this? I don't overfill my tank (but I bought it last November and there's nothing to say that the previous owner didn't).

I noticed it while inspecting the U-Haul hitch installation.

Thanks in advance and happy 4th!

Yes, that can cause it. The fuel will leak out, evaporate, mix with dirt and just eventually build up. Just take a quick glance it at every few months to see if it persists.
