Abstract
In one example, a fuel system includes a fuel tank having a wall with an opening. A fuel float valve has a float and a seal plate on opposing ends of a beam. The fuel float valve also includes a fulcrum about which the beam is configured to pivot in response to a change in fuel level. The fuel float valve is movable between unsealed and sealed positions in which the seal plate is respectively unsealed and sealed relative to the opening. The seal plate includes first and second portions. The first portion seals against the wall, and the second portion is movable relative to the first portion in the sealed position from a closed position to an open position with respect to the first portion.
