It depends on how hard the sending unit is to get at/location. My database doesn't have labor time info for that part. If it is easy to get at, you take the electrical connector loose, screw out the old sending unit, screw in the new one, reconnect. This is just generic info, I do realize you wanted more than that.
Can I ask why you are asking?
