Non-replacable fuel filter?

Hey everyone, I'm in the middle of restoring a 2014 Prius Two that has been sitting for a couple of years. I finally got it to start, but, then it stops about 5 seconds later, and won't restart until I clear the codes. I decided to drain the tank via the power the pump directly and pump it into a gas can method. The flow rate was pretty bad, so I pulled the fuel pump. Sure enough, the gas was foggy, and full of crystals. The fuel strainer was covered in garbage, and i'm assuming the filter is probably just plugged with junk. I can't find a part number for either the strainer or filter. Do I really have to buy an entire pump assembly???
