Pressure relief apparatus for use with fuel delivery systems are described herein. An example pressure relief apparatus includes a body defining a cavity and an annular wall projecting from a lower surface of the cavity. A first valve includes a first valve body defining a first flow passage between a first inlet to be oriented toward atmospheric pressure and a first outlet to be oriented toward a fuel tank. The first valve body houses a first flow control member to control fluid flow through the first flow passage between the first inlet and the first outlet. The first valve body projects from the lower surface of the cavity and toward an upper surface of the annular wall a distance substantially equal to a depth between the lower surface and the upper surface of the annular wall.
