Yeah.  Once you've done it three times n a week, it's real easy!

Grab yourself a 13mm wrench and take of the water pump pulley.  If you do
this, you've got pretty easy access to the sender.  The job is about 8000%
easier if you use the correct tool, which is a deep well 24mm socket.
Easiest is to put the socket on the sender and then put the wrench on the
socket.  Due to space limitations, you're better off using a breaker bar
instead of a ratchet.

Once you've loosened it a bit, it should only be finger tight and an easy
turn off.  Some say you need to use a screwdriver to push the sheet metal
out of the way, but I didn't really need to do that.
