Fuel Dispensers
The pumps on the island that meter fuel into vehicles, fed by the underground tank system.
What it does
A meter in each dispenser measures what is sold. Under it a containment sump catches drips and leaks from the piping connections. Canada's federal code of practice calls for dispenser sumps and leak detection where applicable; in the US new dispensers must sit over under dispenser containment since the 2015 rule.
