Just like the title says, can you replace just the displacer on the sending unit? Have the tank out of my Coupe for some fuel pump wiring work and curiosity got the best of me. The sending unit and gage in my car are fine but I was just curious as all I can find is the entire sending unit. My guess is since they are not a hollow metal float like the older cars and are actually a solid plastic displacer they do not have the issues the old ones did.
