A fuel system valve assembly may include a housing, a spring, and a body. The housing may have a fuel passage defined in part or more by a fuel passage wall. The fuel passage wall may have a seat and a cylindrical section. The cylindrical section may have a constant diameter and may be located downstream of the seat. In use, the body may reciprocate linearly in the housing between an open position and a closed position. The body may be biased to the closed position by the spring. The body may abut the seat when the body is in the closed position.
