Here is a link to an auction for the model I have. https://www.purplewave.com/auction/...2400AJ-Compressors-Air_Compressor-Kansas


The difference you can see the two copper lines on the original set up coming off the head. The smaller one to the pressure switch.

This is the replacement motor they sent me.

This is the line they tell you to use since the newer motor only has one hole exiting the head.
