2003 JGC I6 codes 442 medium leak and 455 large leak

I have asked this a couple of times now, but was hoping for a different response. Clinical definition of insanity. Well that describes this issue. I have replaced or checked the hoses, gas cap (oem), purge solenoid DCP (top left fender), charcoal filter (inside rear bumper/fender well). What is left to replace to remove these codes 0442, 0455 as they keep coming back. Does anyone know what size hoses that need to be replaced in the rear bumper? Would the LDP be going bad without throwing a code? Help is needed. Thanks in advance.
