      5. While lightly pressing down on SST so it does not come off the retainer, slowly turn the handle and remove the fuel pump gauge retainer.
        NOTE:
        • Do not use any tools other than SST, such as a screwdriver, etc.
        • Do not use excessive force when pressing down on SST, as the fuel pump gauge retainer will place excessive force on the fuel suction tube with pump and gauge assembly and be difficult to remove, and parts may be damaged.
        • Be sure to keep the handle level when turning it, as SST may slip off the retainer if the handle is turned at an angle with excessive force.
        • Do not use an impact wrench or turn the handle with excessive force, as parts may be damaged.
        • If SST slips off the retainer, loosen the bolts and reattach SST to the retainer.
