Can't find a part
 

2005 mazda3 got p2188 code looked it up and found most common issue is purge valve. But also noticed one of the vacuum lines on the pressure sensor isn't connected/broken. Looked at the part number on it and can't find one online

The part number is 1s7g-9j559-bb
I keep finding the same part number but not ending in bb, I'm finding other letter combinations. What should I do?
