A float operated fuel tank vent valve has a pair of vent passages with one of the pair larger than the other. A thin flexible elastomeric strip valve has one end attached to the valve body and the distal end bent over the top of the float and attached thereto. The strip valve has a pair of annular sealing surfaces formed thereon each disposed respectively opposite one of the vent passages. Upon refueling of the tank, as the float rises, the strip valve first progressively closes the larger vent passage and then progressively closes the smaller vent passage. As fuel is drawn from the tank by engine operation and the float is lowered, the strip valve is first peeled away from one edge of the smaller vent passage and then completely opens the smaller vent passage. As the float is further lowered, the valve strip is peeled away from one edge of the longer vent passage and then completely open the larger vent passage.
