Hi: I am changing my fuel disconnect on 2009 R1200RT with a kit I got from Beemer Boneyard ( metal instead of the plastic crap, I replaced the plastic one a year ago, now I am replacing it again. and have an extra o-ring does this go anywhere . I have a place on the male part , but it already has one located lower on the part? the info says they include spare, just want to make sure before putting on the body work. Any help would be appreciated. thanks Woody Miller (Hawaii)
