A shear valve assembly for a fuel dispenser that ensures that the energy from an impact to the fuel dispenser causes a shear valve placed inline to the fuel supply conduit to engage if there is a possibility that such impact could cause the fuel supply conduit to break thereby causing a leak of fuel to the environment. The shear valve assembly may be constructed as part of the fuel dispenser during the manufacture of the fuel dispenser, or the shear valve assembly may be constructed separately from the fuel dispenser and attached to the fuel dispenser in the field during installation of a fuel dispenser.
