I am just guessing here, but I'd wager that in AZ they don't test any more
strictly than here in CA, and here they just look at whether the cap seems
to be seating properly and put it on a cap tester to make sure your
non-venting cap doesn't vent. I haven't ever seen them do any more than an
"eyeball test" to see if there's a vacuum line that might go to a carbon
can. I think they just assume your tank vents lines are all there. I've had
a "gas cap fail" before on my nasty ol' dodge van, but it was just not
seating flush. I've never even heard of anyone failing on a carbon can not
hooked up.
