Abstract
A double-walled flexible dispenser sump connection system prevents fuel leaks into a dispenser sump located below a fuel dispenser. An inner flexible connector and an outer flexible connector are configured such that the dispenser sump connection system may be installed on newly constructed fuel delivery systems or be retrofitted onto existing fuel delivery systems in order to bring them into compliance with recently environmental regulations.
