1987 K5 fuel gauge

First post to these forums, and I am really impressed with this website. Looking forward to upgrading my membership soon.
Anyways, hit a mud hole the other day and on my way home noticed my fuel gauge wasn't working. The needle is stuck on empty, and I put in $40 in the tank and it is still on empty. It is like something unplugged. So my question is, any ideas what could have happened? Any way something obvious got unplugged/rattled loose?
Searched the forums, couldn't really find an answer to my problem.
Thanks!

Check the ground at the tank. Do a search of my posts and find the post that has the GM 90 ohm gauge diagnosis.
