Gas quick couple problem
i have an o7 harley ultra which since it was new it would ping in the mountains. 3 times it would not start and i had it towed 2x to the dealer and they disconnected and reconnected the quick couple off the tank and it ran fine for a couple of months. last year it quit several times and i dis and re connected the coupling and it ran for a little while. i took it to the dealer and they replaced the quick couple after replacing the vent valve (the vent valve was not the problem) and i had to return to the dealer the same day. But since the coupling was replaced the bike runs better and stronger, does not ping at all, and has not had a fuel problem since. The old quick coupling i could move up and down a bit like it was loose. the new one is very tight.

Thanks for the info. It's something to keep in mind if that sort of problem arises.
It would have taken me a long time to figure that one out. How long has it been since it was "fixed"? How many miles?
If you think about it, post again in a few months to let us know if that was the final fix for this problem.

I used to work were they made the disconnects. I helped design and build the machines to assemble and test them
.. There can be a couple issues with couplings like the ***** wearing and letting the coupling close enuff to slow or stop fuel flow. They also if decoupled a lot and not re coupling them keeping the fitting as straight as possible can shear the outer o-ring causing fuel leaks. Seems the o-rings dont like ethanol either.. Ive helped a bunch of guys out here repair the fittings o-ring wise but if its a problem with the ***** being wore to the point of decoupling the fittings somewhat to cause little or no fuel flow then thats a replacement fitting to cure the problem.
Happy riding
