Is the purpose of the clicking fill caps merely to ensure one does not overtighten?
Mine broke, or at least the ratcheting part did (oil fill cap, not gas).:bangheadyo da Shadofax,
This is in 96 Bronco Owner's Guide (aka, "Manual") by Hiller Ford;
"...To replace and secure the fuel cap; place it in position and rotate it clockwise until it clicks (ratchets). Doing so will not damage or break he fuel cap. The ratcheting mechanism allows the fuel cap to be sealed without overtightening..."
