A Stout Tool to Remove and Install Fuel Tank Lock Rings without Damage. Channel design on body allows 2 interchangeable sets of legs to adjust to fit rings from 4" to 7-1/4" and keeps the drive centered. Works on the smaller GM serrated rings and traditional rings. New leg set works on many 2004 and newer vehicles including Ford F150, Chevrolet pickups, Chrysler/Dodge mini vans, PT Cruiser, Dakota and Durango. Design is compact so the tool is not left hanging over the work area with the potential of hitting other components.
