I work at a small repair shop, I put a scanner on this vehicle and it came with these two codes po172b bank 1 system to rich, po175b bank 2 system to rich. Could this be caused by the fuel pressure regulator?

Do you
have the same problem?

Yes it very well could. It will be a direct leak into the fuel system
