If you're having trouble finding the components, ask one of the guys working in the shop at the base, some may be ex mechanics, at least they were at Ft Bragg. If you check all lines & gas cap seal & don't find anything, it could be a failing LDP(leak detection pump), that is a common problem. The base may also have a scanner & smoke machine to run the tests on the evap system that you could use. To make matters worse, it could be an electrical problem, such as a broken wire at the purge or LDP or the ECM not commanding them on/off, but those are a lot less common.

P0442 - Evap syst (small leak)
P0455 - Evap syst (lrg leak)
These can be tricky to track down without the right tools. Those hard plastic lines can become brittle over time & crack. You didn't mention, but if any fuel tank or pump wokr has been done recently, you want to check the line connections to the pump or pump sending unit o-ring. If no leaks from lines, filler tube, gas cap, etc it could be one of the solenoids not sealing properly when it is supposed to. GM's are notorious for canister vent valves not sealing or failing all together.
