8.149. If a submersible pump is installed in a motor fuel dispensing outlet, the dispenser must have a fusible safety valve set not higher than 70 °C, firmly attached to the pump island and meeting the requirements of CAN/ ULC-S651, Standard for Emergency Valves for Flammable and Combustible Liquids, published by Underwriters’ Laboratories of Canada.
That requirement also applies to a tank installed or altered at a level higher than the base of a motor fuel dispenser. If it is an aboveground tank, it must have a mechanical or electrical anti-siphon valve installed where the piping connects to the tank. The safety valve must also be installed so that the shear point is situated in the zone extending 25 mm below the base of a motor fuel dispenser to 13 mm above the base.
