Just doing some service in prep for this coming Friday's run down to Overland Corner RTE and thought... Hmmm that felt odd.
Wound it out and turned the cap up tight again by hand but its not good.
Took it back out and its cracked through along the line of the thread almost all the way round just above the "O"ring. It looks like its been growing for some time as the mid section is darker than the rest.
The obvious fix is order a new one which I will do in the morning... but...
What models do these caps interchange with? Does anyone know? Would one from a Wing fit?
