Gauge fuse being hot when you turn the switch on pretty much gurantees that part of the wiring is good and working like it's suppose to.

That's not looking to promising right now.

It would be normal to get some kind of ohm reading while testing the green temp sending unit wire under the hood. At minimum it would've had temp light bulb resistance and ever how much resistance/ohms the fuel guage has. This is just because of the way the printed circuit is layed out with one power wire going to several different things.
So depending on what kind of reading the tech guy got....there may not be a short at all. It would be nice to know what kind of reading he got.
If you haven't all ready tried; turn the switch on and touch the temp sending unit wire straight to the engine somewhere. That would make the temp light come on if (BIG IF) the temp bulb is getting power the same as the oil light.
Temp bulb test coming on while cranking is a different set of ground wires that works through the ignition switch in crank position only.
So ground the sending unit wire and let us know what happens. If the temp light comes on, things aren't quite as bad as it seems.
Got to remember that bulbs or sockets not making good contact on the back of the cluster might be the whole problem.
Good luck again
