Pray tell, how do you tell that it is upside down? My sender unit arm
points off to the right of the car...

Here's an interesting story about sending units... When my car was still in
pieces in my barn, but I'd finally gotten it to run, I put gas into it...
about ten bucks' worth, which half fills it here in Canada.
So I was running it around the farm when I was bored (The bonnet and
everything else ahead of the rad were still off the car at this point :-) )
an dI noticed that the gas gauge kept reading HIGHER.
Disassembly proved that the sending unit had been installed UPSIDE DOWN!
Has anyone else ever seen this? Could it possibly have been this way since
the car was new? (It had been stored since 1986 when I got it) The lock
ring was pristine...
