Mine was not dripping from the threads, but from the plastic center piece. Be sure to replace it with an NOS unit. I got a new one from NAPA and it did not work properly. Got one from Rick E. on EBay and worked perfectly.

Exactly. Can leak from electrical contacts. I got NOS from CRT. Also, there is a short and long switch. Get the right one.
