A fuel system valve assembly may include a housing (38), a spring (40), and a body (44). The housing (38) may have a fuel passage defined in part or more by a fuel passage wall. The fuel passage wall may have a seat (60) and a cylindrical section (58). The cylindrical section (58) may have a constant diameter and may be located downstream of the seat (60). In use, the body (44) may reciprocate linearly in the housing (38) between an open position and a closed position. The body (44) may be biased to the closed position by the spring (40). The body (44) may abut the seat (60) when the body (44) is in the closed position. |
