TIA for any help!

That item is a strainer for your water pump, to keep large chunks of whatever you poured into your fresh water tank to get into the water pump.
The foaming problem does sound like air in the lines. Does it stop after a few seconds, or does it spit and sputter all the time you are drawing water? Does it do it on hot and cold, or hot only? It sounds like water is draining back into the tank when you turn the water off, and the lines have to refill.
