Now I'm Not sure too. Maybe we're flipping terms for some cars. I don't have gas caps for many pre 80's cars and many catalogs no longer list gas caps for them. Or might list but no accurate pictures of them.
Stant book doesn't say non-vent/vent in gas caps for Fiero or anything else.

Many caps, including replacement caps for Fiero, have a Warning that maybe pushed out Gas when you open them and why I think many can get confused. Even this 80's NOS Stant cap... (BG817, G817, later 10817)

On back just says: Emission Control Type

Worse, some pre-emission cars had non-vent caps because system had other vent port(s) and no air flow at the cap. Many had just 2 or 3 stamped metal parts and a gasket.

Is correct for small engines and others. Air moves in Both Directions thru the vent in the cap or in the tank.

Mine locked before i modified it to stainless. It would still have to be broken into to open it.

These are not for fiero but could be modified with similar parts.

Best part of the Fiero is where the gas tank is located.
I went to a car dealer years ago when gas spiked and a bunch of his cars had holes drilled in the tanks to get at the gas.

This was a problem with the Transit vans not that long ago people would crawl under them and cut the fill hose that would apparently drain the tank. The dealership was backed up with Transits waiting for replacement filler hoses.

Honestly with the Fiero im not worried about gas theft. I could never get much out of gas tank with all of the time in the world and a really long hose. I have always had to drop the tank or at the very least jack it up and pull the filler hose.... plus my Fiero has been enjoying life in my garage :P .

A neighbor of mine who owns an auto repair shop said that he can get a locking gas cap removed in about 1 minute with a screwdriver and a pair of vice grips but I believe that the Fiero is a very hard car to siphon gas out of with a hose. I've never been able to do it

If they really want your fuel...
many simply punch a hole in the tank and drain that way.

I posted above.

Transit and other w/ fill hose cut likely easy for siphon/pump use. Most times, the cut line itself doesn't drain the tank.

Even Diesel vehicles get holes in tanks or lines cut because often easier then trying a siphon "the normal way" even if are unlocked and easy access.

Fiero is harder then most and many other cars because of low clearance.
Anything w/ better clearance is easy target for cat and/or fuel theft.
Some Jeep and others have easy access to engine bay and gets battery stolen too. Many Trucks, SUVs and jeeps have very big AGM batteries that sell high as "used" batteries or as "Scrap..."

Honestly, you only need a big pair of Chan-L-Loc pliers. If you squeeze the sides of the cap it will grip the inner part and unscrew. You wouldn't believe how many customers forget to leave a gas cap key when they drop their cars off for inspection.

https://6abc.com/allentown-...aling-fuel/11651886/

because many newer "cars" have "rollover valve" in the filling port that act like Bandit Blocker

In Other stories across US alone, many steal gas right from station's bulk tank buried in ground Example:

The idea of punching a Fiero tank is a bit ludicrous. Way too much work to jack it up. So siphoning is really the only threat.

Just like the catalytic converter, the Fiero would be one of the last targets a bandit would go after. Not only the location of the tank, but the capacity. On average the Fiero would have 6 gallons and max of 12. Compare that to your neighbors 20 gallon SUV. Also if you need 20 gallons, would you rather commit two crimes or one to get it? The penalty is the same if busted whether you siphoned 5, 10, or 20 gallons. Now if you need to hit 2 Fieros to get your 20 vs 1 SUV, why subject yourself to having to do the job twice and being charged with 2 counts of theft rather than 1?

I think it's rather silly to buy a locking fuel cap for your Fiero but whatever helps you sleep at night.

Yes, This site is for Fiero...
BUT...
A lot that read this thread HAVE other vehicles that are targets to punch the tank, cut the cat, etc.
And buying Locking Gas Caps is useless for them too but a pain to the owner and others working on them.

A lot newer vehicle has "anti-rollover valve."
I'm guessing Many are simple ball in cage check valves that never let siphons in and why More thieves are punch the tank.
At any rate, these valve make buying locking cap a wast of money.

Ford Pinto And More had Cosmetic Caps you see all the time and they fall off or are stolen and why many had locking caps. Those caps can't be left open or easy to have rain and dirt getting in the tank even w/o others doing crap to the car and that's far before E10 problems.
Web search Mavrick Pinto and other "Vintage" caps...

Jeeps have a Very Long History of Battery Theft and other engine parts stolen because of the Crap bungees holding the hood down on some models since WW2. Any with that needs to add DIY or Aftermarket hood locks.

Before remote hood latches became standard, was easy to steel batteries on most cars.
Many years ago, I had a chain lock under the grill of my car because worked in big stores and many things stolen in the parking lot including car batteries. I leave nothing easy to see yet still have car broken into a few times digging thru glove box and more.

Battery Theft is often mean they cut or break other parts making to fix harder and expensive.
Most places Won't repair a punch tank. Only replace them for Business Insurance reasons costing High $.
Same goes w/ cat cutting, worse when they wreck/cut O2 sensor(s) and other wiring.
