That's pretty much it Edge. Should be threaded into the lower part of the filter housing, probably in a tight spot. Should take a 17mm open end to loosen. Getting the replacement threaded in isn't terribly difficult, it just takes a little finesse to get started without stripping the aluminum due to being in a tight spot. Cost is ~$70 for the sender.

Ooops...just noticed this was the 6 cyl. Not sure where the sender is located. Don't these have the filter top mounted?

edit: I just looked at my EPC for the 94 320. It appears the filter is mounted in the classic position on the side of the block. Sender is mounted at the bottom of the filter housing. I wanted to take a screen shot for you but I have no printer and my laptop wouldn't permit it...unless I'm doing something wrong???
