Nota, if you want to do it right, picture of both ends would be good, panel and outlet box.. Need wire size, breaker size, gauge of wire(awg) size of conduit, current demand of appliance.

What year was house built? 1980's and before, emt served as the ground in florida. Ive fouind some emt corroded so bad, or loose connections in the walls, that GFIs don't work. I've been pulling new grounds, or running new homeruns back to the panel when possible.

Also, If the conduit is running through concrete, I strongly recommend pulling new wire(s). I've seen some so corroded so bad they no longer conduct, and spalling (concrete guys) splicing wires and covering with cement.
