There is a hairline crack on the top black piece of piping (where the wires are coming out). We have wrapped with yellow plumbers tape and it held for awhile but is back to leaking. We need to replace that entire middle section of pipe. How hard is this to do? Just disconnect the wires, disconnect the pipe and replace with a new piece? Any idea what this piece is called so I can try to find it online? Thank you!

Correction - It is just the gray (not black) top piece that has the crack.
