Approval marks decide where a can may legally be carried

The best fuel cans for 2026

A fuel can carries petrol for a generator, and it is one of the few products on this site whose specification is legal before it is practical. Approval marks — the standards printed on the can and the certifications listed in the description — decide what may be transported in a vehicle and stored in a garage, and those rules are national. This page reports what the maker states and does not interpret the law. The practical specifications follow. Capacity is the nominal volume, and the useful figure beside it is the expansion space a compliant can leaves above the fuel. Material separates metal from plastic, and the plastic ones are made to a specification that resists the ethanol content of modern petrol; behaviour with static electricity differs between the two, and the maker’s instructions on filling and grounding are the reference. The spout is where the design work shows: a vented, self-stopping spout pours a generator tank without a funnel and without spillage. Sealing and the gasket decide whether the garage smells of petrol. We compare capacity, approval marks, material and static behaviour, spout and venting, sealing and stated fuel compatibility.
