I don't know why the sending unit would be different, but I'd guess you
still could use that part of the one from your present tank.  All you
really need is that new plastic cover part.  I'll bet the plastic broke
when someone tried to undo the banjo bolt.  I broke one on a parts car
trying to undo that bolt to get to the fuel pump.  I'd be sure I have a new
cover to install before disassembling further.
