Just found the fuel flap on the car open. Nothing was stolen as tank was almost empty anyway.

But a bit paranoid now. Are there are security measures worth taking that don't include a dashcam? Do fuel cap locks actually work?

    Do they work? Well a determined thief would be able to defeat it, however it makes it more hassle so more likely they would move on to the next car. However most "gasoline theft" is completed by drilling into the fuel tank so it wouldn't matter what lock you put on the cap or flap! I recall seeing a documentary about this happening in Eastern Europe back in the 50s... Was it during the Hungarian Revolution?
    Ah, I assumed they would use a siphon to drain the fuel.

    You might have just forgot to close the cap, I see it all the time. Some cars even say you've left it open.
    Your cap should lock and unlock when you open the doors, or you'll have a manual release inside the car.
    If somebody's going to nick fuel they'll do it from a big lorry or tanker

    It should! Go lock the car then try opening it. The ones that don't lock themselves are the ones you put a key in to unlock.

    I didn’t think you could siphon fuel these days, and instead they just put a container under the car and cut you tank or lines to it.

    I may well be wrong, but I thought that most cars made this century had some sort of anti-syphon feature to stop you putting a tube down through the filler cap into the tank to syphon off fuel.

    I don't think you can siphon from car fuel tanks. They're all anti siphon afaik

    The jury is out on whether fuel can be siphoned from the fuel pump. Any one able to shed light?
    No you can't.

    You can't siphon modern cars fuel so need not worry
    I never knew this!
    I always thought it a step backwards when they stopped doing locking fuel caps

    Easy enough to pull pipe/s off fuel tank or even just stab the fuel tank to drain the fuel. Most fuel tanks are plastic these days too making it even easier etc. If someone wants the fuel they will get it.

    Most fuel flaps being open are just accidental, if it doesn't click home then it can just pop open while driving (or when you lock the car). You don't tend to look at them that often so it could have been like that for a while. I wouldn't worry about it, as said plastic tanks and pipes that are highly accessible are much easier, quicker and quieter to attack.
