Abstract
Pressure relief apparatus for use with fuel delivery systems are described herein. An example pressure relief apparatus includes a pressure relief system coupled to a body of a fuel cap to define a first side of the body and a second side of the body. The pressure relief system comprises a plurality of fluid valves to enable fluid flow from the first side of the body to the second side of the body when a first pressure differential across the pressure relief system from the first side to the second side is greater than a first reference pressure and to enable fluid flow from the second side of the body to the first side of the body when a second pressure differential across the pressure relief system from the second side to the first side is greater than a second reference pressure.
