JoeFo,
     Interesting enough I think that it is not
pressure that is important for the working cap but
negative pressure.   It maybe that this smog test
requirement is doing you a favor because the engine
creates negative pressure in your gas tank by sucking
vapors from the charcoal canister that is connected to
the gas tank and that rather elaborate series of hoses
and plastic tanks.   In some models a bad cap can
cause poor engine performance and even  do damage to
an engine and the cat.   Seems reasonable that you
would want to replace a bad cap.   gary

JoeFo,

They've been doing this for a couple of years. Your
cap can be
releasing
gasoline vapors. Makes total sense to me. I brought an
extra cap to my
last
inspection just in case. I haven't failed yet.
However, I have seen
cars with
dirty rags for gas caps turned away.
