Hi Dave,
You're correct about finding a barrel (about a foot long) in 940 fuel tank which acts as a fuel level sending unit, within which contained two long rods (plastic coated) with coiled wires (resistance wires). And there's a cylindrical plate float (with internal contact points) riding between those long rods to connect them electrically thus changing the resistance to affect the fuel gauge.
I think what John refers to in his question is about two small chokes (less than 1 inch long) at the in-tank fuel pump motor electrical connectors. My 1994 940 has it.
