This is not correct. There have been some changes to the fuel inlet nipple and the vent nipple (especially the inside configuration of the vent nipple), but the change on the KLR650 CVK40 to the 'non-removable' nipples (they are, of course, removable and replaceable using the parts the Harley guys have made) did not happen until the 2010 model year. The OP's 2008 should have the easily removable nipples that do swivel.
The 'new style' nipples were really odd in that they were not new in 2010. They had been used on the Vulcan carbs 20 years ago. ¯\_(ツ)_/¯
Oops, sorry for the bad information. I have a 2012 KLR with a non-swiveling fuel inlet, so I mistakenly assumed all Gen IIs did not swivel.
Here's a pic of a replacement fuel inlet for the non-swivelers. As you can see, it's solid brass and is merely pressed into position after removing the brass stub.
