Unplug the sender and see if it goes down.
 yes w key "on", unplug it at the tank & if it goes back to E either the sending unit inside the tank is shorted to ground or the wire from the female connector forward to the dash is grounded somewhere along that line under the carpet.
After I changed from a 3/8" to a 1/2" fuel pickup, my gas gauge always reads Full, too. Does that sound like the sending unit is shorted as mentioned above, or could it be the float arm adjustment being different between the two pickup assemblies?

Because this only happened after you changed sending units I would think it had something to do with the float arm

What they said, key on, pull female connector off & if it goes back to E then plug it back in & if it goes back to/stays at F then run it out of gas as close as you dare and pull the sender & check it's ohms w the float "up" and "down". iirc the specs are 73? & 10 ohms but with it reading full constantly then it'll be apparent where it's grounded. W the sending unit electrical located halfway up on the side of the tank the whole thing gets submerged when the tank if filled and it's in effect a dead short to ground just like when you ground the female connector and that's why the gauge stays on F for along time when you first fill the tank until the level goes down far enough so it's actually below the windings then the gauge starts to show the correct reading.
