Ear Clamp Pliers to really get the clamp tight. I suggest getting a new seal for the pump as it was hard to get the old pump out of the seal and would not trust it. I would also suggest replacing the Diverter Motor and buy an extra Diverter Motor seal if the Diverter Motor comes with a seal. I ripped the new seal trying to get it in place and had a small leak, so lucky I had made a mistake and ordered an extra. replacing the Diverter cost an extra $32, but was worth doing it while I had the dishwasher out and pump out of the way.
Items I replaced and used to fix my no pump run issue :
Pump seal # WPW10538166
Dishwasher Diverter Motor W10537869
Diverter seal WPW10195677/W10195677
