Ratcheting Style Gas Cap Set Vented and Non-Vented

This black steel gas cap set is ratcheting style. The right cap is vented and the left side is non-vented. Caps are screw in type.
Cap set features low pressure relief vent recessed in cap to clear the filler neck vent tube. We suggest to use this cap set on bobbed and quickbob tanks. All tanks or tank sets will require hand fitting to give correct alignment for dash and fuel line fitment. Dash will also have to be shimmed when installed, to achieve correct height. *NOTE: One cap is right threaded and the other is left threaded.
