A valve assembly is provided for venting pressure in a fuel tank. The valve assembly includes a float member that is movable between a first position and a second position. A flexible seal is supported on the float member. The valve assembly also includes a valve port that may define an orifice and a closure surface surrounding the orifice. The closure surface may include textured features that are configured to engage a surface of the seal when the float member is in the second position. |
