<p>In one example, a fuel system (10) includes a fuel tank (12) having a wall (36) with an opening (38). A fuel float valve (24) has a float (34) and a seal plate (40) on opposing ends of a beam (32). The fuel float valve (24) also includes a fulcrum (30) about which the beam (32) is configured to pivot in response to a change in fuel level. The fuel float valve (24) is movable between unsealed and sealed positions in which the seal plate (40) is respectively unsealed and sealed relative to the opening (38). The seal plate (40) includes first and second portions (42, 44). The first portion (42) seals against the wall (36), and the second portion (44) is movable relative to the first portion (42) in the sealed position from a closed position to an open position with respect to the first portion (42).</p> |
