Abstract
A relief valve is provided for use with a fuel system. The relief valve may have a housing forming an inlet, an outlet, and a central bore fluidly connecting the inlet to the outlet. The relief valve may also have a valve element disposed within the central bore of the housing and being configured to move between a flow-passing position and a flow-blocking position. The valve element may have a passageway continuously communicating the inlet of the housing with the outlet of the housing. The relief valve may also have a resilient member situated to bias the valve element toward the flow-blocking position.
