This works on all NC31 / NC32 and NC51 VERSION 1 Cleaners but is 50' long instead of the original 60' long that came with the NC51 originally.

Please note that there are TWO versions for this part. To tell which version you have, you need to open the cleaner up and look at the pump motor itself. Pictures are included of the pump motor to help you identify which one you have.

VERSION 1: The sensor wheel and cable pressure fitting are on the same side

VERSION 2: The sensor wheel and cable pressure fitting are on opposite sides

Please indicate which version you need upon ordering.
