    Welcome to the forums from UT!

    We have a couple threads on here regarding locking gas caps.

    This one seems to have the good stuff! https://www.tundras.com/threads/gas-cap-w-key-lock.3182/

    Hope it helps!

    FWIW...I believe the Tundra has this, I could be mistaken. I read this recently.

    A little research into modern-day siphoning, revealed that all new cars and trucks have an anti-rollover valve on all the openings into a gas tank. These valves also act as a siphon prevention system, which is the reason why nearly all the siphon devices and pumps sold these days are useless. However, there is a way to do it without damaging the vehicle if you have the right tools.

    Most gas thieves today simply drill a hole in the polymer gas tank, take what they can, and let the rest run out on the ground.

    The anti-rollover valve is a ball or butterfly valve. This leaves enough room for gas to flow through the fueling tube into the tank, but if the car flips over and gas begins to flow the other direction, the ball moves to the inlet and blocks the gas from escaping or the butterfly flap closes.

    Thats just great. They have money for a cordless drill and a place to charge it but no cash for gas.
