Abstract:
A wrench cap adapted to remove a cover of a fuel filter housing, wherein the cover includes a top surface with a peripheral portion and an array of radial ribs having selected radial extent terminating at the peripheral portion to define a rib-free area of a selected width and maximum diameter, the disk cover having a threaded portion thereon for threadably coupling with a threaded mouth of the housing to retain a filter element within the housing, the wrench cap comprising:a disk having a diameter larger than the radial extent of the ribs; a flange extending from the disk and enclosing a space having a diameter larger than the radial extent of the ribs but less than the maximum diameter of the peripheral portion, the flange having an edge adapted to engage the peripheral portion of the top surface of the disk cover; a plurality of lugs spaced from one another and extending inwardly from the flange, the lugs being adapted to engage the ribs in a circumferential direction to apply torque to the cover, the flange being adapted to engage the ends of the ribs in the radial direction to keep the wrench cap from slipping radially with respect to the cover, and a coupling on the disk adapted to couple with a wrench handle for applying torque to the disk.
