I have a crossfire 68/45 and i am having a problem with the fill nipple o-rings. i can play maybe 2 or 3 times and then the o-ring inside the fill nipple will bend out of place and leak. I know i can just buy a 5-pack of the o-rings for like a dollar and just keep replacing them, but i just wanted to kow if there was anything else wrong that i should know about.
if the o-ring keeps coming off the checkstrut, I would take a look at the checkstrut to see if the o-ring groove is damaged, or if it's just shallow. it sounds like the check strut may not be the correct one for your fill nipple, or that it just wont hold an o-ring securely anymore.
