Abstract: A flow through pressure regulator apparatus and method for directing a flow of fuel and reducing noise generation within a fuel system. Present invention includes a lower housing having fuel inlet where fuel flows through the fuel inlet and communicates with a valve biasing member through a fuel chamber. The valve biasing member permits or inhibits fuel flow through the fuel chamber by opening and closing a valve element. The valve biasing member comprises a flat disk having at least two reticulated concentric rings coupled by at least one bridge. As fuel flows past an open valve element, the valve biasing member diffuses the flow of fuel. A fuel cover directs the flow of fuel from the valve biasing member to the fuel outlet.
