A fully-integrated, flow-control module for top-fill fuel tanks operates with a fuel line attached that supplies fuel under pulsating pressure. There are two bleed paths in the module, which open and close sequentially in response to the position of a fuel float within the module. In order for a main valve plunger, which controls fuel entry into the tank, to fully close, both bleed paths must be closed. A first bleed path closes first, followed by closure of the second. For the main valve plunger to fully open, both bleed paths must be open. The second bleed path opens first. Movement of the main valve plunger is controlled by both a biasing spring and pressure beneath the plunger. Pressure beneath the plunger builds up to a level sufficient for the biasing spring to fully close the plunger against a valve seat when both bleed paths are closed.
