You will be very, very lucky to find one on ebay - I know, because I've been looking for one for many months now.

Assuming you mean the later, flange type fuel sender then yes, completely agree with Dai - they are rare and expensive.
I've accepted that, next time I need one, I'll instead set about repairing the one I've got. The rheostat is 'standard' 0-100 ohm in common with many other sender units, so a cannibalised repair should be possible. If, as happened to me, the connections seem to to go open circuit as they pass through the square flange, then that can be caused by fractures in the actual conductors within the plastic bushing. There is a way to fix this, but it's a bit involved and it really needs to be reliable, given its location.

just a heads up ,
thinking of going into restoration of the fuel sender units 

including 
electrolysis removal of rust etc 
replating of metal parts involved 
rewinding the rheostat
resoldering the connections 
providing new cables to the pump 

have found some suitable cable for the rheostat 
which will involve testing the process (length , resistance , terminations )

fingers crossed it goes all ok .....soon
