A vent valve assembly for use with a fuel tank may comprise a housing having outer and inner wall structures that define a chamber therebetween, and a float located inside the chamber and configured to be translatable relative to the housing along an axis. The float has an orifice extending along the axis. The inner wall structure of the housing is disposed within the orifice of the float, facing an inner surface of the orifice. The vent valve assembly also comprises one or more guiding features located on the inner surface of the orifice, and one or more mating guiding features located on the inner wall structure of the housing and configured to mate with the guiding features. The guiding features and mating guiding features cooperate to guide translation of the float relative to the housing along the axis and restrict rotation of the float about the axis.
