Abstract: A shear fitting for coupling a downstream vertical conduit to an upstream vertical conduit in, for example, an underground suction-type fuel delivery system, includes a hollow body defining a fluid flow passage between an inlet in an upstream body portion and an outlet in a downstream body portion. The upstream body portion is configured to be removably coupled to the upstream conduit, and the downstream body portion is configured to be removably coupled to the downstream conduit.
