The KIT1640 requires an engine shaft that is a staight 3/4" shaft with a keyway. On the pump side it needs the standard Hypro flange with the 3 bolt holes. This is the flange found on the D30, D50, the D403 and a few more Hypro diaphragm pumps.

Hope that clears it up. We have plenty of inventory.
Thanks again. Here's another question: would my D403 regulator fit onto the D30?
