98 FLHRC-I fuel line leak

I have 10,000 miles on a 98 Road King with fuel injection & the fuel return line leaks where the fuel line male quick connect snaps into the female hex nut fitting that goes into the gas tank. I replaced the O ring on the hex nut to gas tank fitting, but that is not the problem. This happens on cold mornings & the fitting will drip until it is warmed up by the engine. The fuel line male quick connect swivels in the female hex nut fitting & I have jiggled it around trying to get a better seal with no luck. This quick connect assembly cannot be operated like the type that is on the TC's, which I believe can be operated like a air hose quick disconnect. I have a manual & can change out the fuel line & connection, but I am hoping that there is a design improvement on the replacement so this does not happen again. Any guidance would be appreciated.

Did you ever get this sorted out? If so, what was the problem?

I recently had the same problem on my 00 bagger the o ring in the check valve that screws into the tank was bad. if you take it to the dealer they can replace the o ring. I changed the check vavle myself for a cost of $25.00 and about 2 hours of my time. problem solved.

My '98 Ultra has started leaking fuel from the supply and return fuel line quick disconnects. The inner 'O' rings in the qd's are leaking and fuel comes out where the quick disconnect swivels on the tank fitting. I drained the tank, relieved pressure off the fuel pump and have the lines disconnected from the tank. I can't figure out how to remove the fitting from the fuel line so I can get to the inner 'O' rings to replace them. My My official factory manual does not explain disassembly/ reassembly of the qd's. Does anyone have knowledge about replacing the inner 'O' rings?
