      Evap purge hoses

      Hello all,

      I am facing a "evap purge low flow" P0497 code. I have replaced the EVAP purge valve under the intake manifold as well as the gas cap, and the code has returned. I theorize the there is potential the EVAP purge hoses may have been pulled apart at the union between the front and rear segments of the hose.
      I didn't realize until recently there were actually two separate hoses. My question is whether anyone on the forum knows where the two hoses meet? I have spent time under the car looking for blatant leaks, but I have not removed the fuel line cover or anything beyond the fuel filter location. It is my understanding the hose snakes over the rear differential, ultimately reaching the charcoal canister. I have attached the images below to depict the connection I am referring to. Any other suggestions to diagnosing this code is also welcomed.
