Huge fuel leak, heals itself perhaps???
I've had my K1300GT opened up a bit to install a power commander. Unfortunately, I clumsily broke part of the plastic fuel rail and so acquired a replacement from Ebay.
I put everything back together and fired the bike up before as a test before reinstalling the fairings. All was well until I noticed a pretty big trickle of fuel exiting the bottom of the bike. I shut it down and thought about what I might have missed during installation. Nothing came to mind.
So, one day later I took out the airbox and hooked up the tank so that I could see if I could see the leak when the fuel pump powered up. I did this and the leak seemed significantly less, and I couldn't actually see where the fuel was coming from.
Thinking on this a bit more, I remembered that the o-rings between the segments of the fuel rail did not seem that tight. In retrospect I probably should have replaced them, but they're quite a hassle to get to now.
Is it possible that these o-rings are swelling now that they have been exposed to fuel again after some unknown amount of time sitting dry? Is it possible this leak will seal itself in another day? Does anyone have any experience of something like this?
Obviously, if there's something I might have missed feel free to point it out, but it's not super complicated. The hose from the tank goes to the center section of the fuel rail, then there are o-rings sealing that to the two "arms" of the rail that each go to two injectors. There's one more o-ring to a pressures sensor. I can't actually see any leaking, but it is hard to see in there and impossible to get fingers in to poke around...
I guess I can order new o-rings and spend an evening taking it all apart again, but I'm tempted to wait and see if the leak is gone in another day!
