I changed the pump and also discovered the coin trap was wearing thin because it was rubbing against the sheet metal. So I replaced that as well.
It took about 15 minutes to remove the coin trap and pump and about 20 minutes to install.
The shipping was amazingly fast. I received the parts the next morning. I'm talking I ordered the parts before noon, chose the "fast shipping" option and received parts the next morning around 8:30 AM.
