Ford introduced its capless fuel filler technology in the early 2000s with its GT sports car.
The system is designed to make fueling as easy as possible while making it difficult to get fuel out.
Held in place by latches, the spring-loaded trap door opens only when a standard gas-station fuel nozzle is inserted into the filler neck.
However, if you want to fill up using a jerry can, you'll need the specific OEM-supplied funnel that came with your vehicle.
Theft finds a way? Despite designs and anti-theft measures, creative thieves have found ways to bypass these systems.
Rising gas prices have led desperate individuals to steal fuel, as seen in cases like Tasi Malala's $3,000 repair bill.
While capless fuel fillers offer convenience and anti-theft logic, they also present practical issues like dust ingress and frozen flaps.
Other manufacturers such as General Motors, Stellantis, and Honda have adopted similar systems.
The technology has become increasingly popular, with mainstream adoption coming in the 2008 Ford Explorer and Mercury Mountaineer.
While the technology has improved, it's not foolproof against determined thieves.
