  • Patent number: 4312753
    Abstract: An intank fuel filter of flexible woven plastic cloth having spacer means comprising protuberances secured to at least one of the flexible walls and projecting toward the opposite wall to hold the walls against collapse blocking fuelflow. The protuberances may extend completely through the flexible wall to provide external spacers to hold the filter away from the fuel tank wall. Tensioning of certain filters herein with a stiffly resilient rib structure (within opposed plastic cloth filter walls sealed at their marginal edges) against a bottom wall of the fuel tank permits fuel intake even if fuel is low and such bottom wall bows away from the fuel pump.
