Quick Disconnect O-Ring
Just wanted to share a simple solution to anyone else who may have issues with a leaky quick disconnect on the fuel tank. Recently, after re-installing my tank after paint, the quick disconnect started to leak...leak pretty profusely actually. Anyway, the Harley dealership tried to sell me an entire new quick disconnect. I insisted that there had to be an o-ring inside the disconnect, but the parts guy swore that there was not. After refusing to spend $58 on a new disconnect, I drained the fuel from the tank, removed the disconnect, and removed the cracked o-ring (the one that the parts guy said did not exist). A quick trip to the local parts store and I found the o-ring for under $1.

More often than not "parts department" employees are not mechanics, they don't know the intricacies of how things work. They will attempt to sell what the "easy fix" is, rather than what's really needed. Some of them do know what's really needed and will try to sell the whole assembly because they get a commission.

Moco had a recall on my '04 FXDLI for a leaking QD, several years ago. I refuse to take a perfectly running bike to a dealer for a recall for fear they will not return the bike to me in the perfectly running condition in which they received it.
If and when it ever leaks, I'll do what you did.

Item 19 CHECK VALVE, OUTPUT, W/ REF # 8, 9
Item 20 FUEL LINE, FROM TANK TO INTAKE, W/ 10038A (hose clamp)
I've had that same problem. You have to be pretty careful reconnecting the fuel line or that o-ring can get pinched. It's the same size o-ring as the oil drain plugs...if I remember correctly it's a #41.

If the o-ring is split, no doubt you need to replace it. The first time I disconnected and reassembled it I had a small leak, I disconnected it and used a small amount of Silicone grease and have not had a problem since. I Use a little every time I disconnect it.
The problem with the parts guy is there is no number in the book to replace that o-ring and he would be guessing what the correct o-ring would be.

do you have to remove the disconnect to get hte o ring out? Or can you leave it together and get it out with a pick tool or something?

You can get to the o-ring without removing the quick disconnect but you are going to have a fun time doing it. The best advise is to get as much fuel out of the tank as you can, unscrew the disconnect so that you can at least move it slightly, then remove the o-ring. Be careful not to pull it out much because the hose that connects to the disconnect to the fuel pump on has about 1 inch of slack in it.
If you do decide to try to replace it where it is, make sure that it has only a little fuel in it and put an absorbent rag on the primary. You will make a mess.

Thanks for the tip on the slippery install. I should have done that before I popped the thing back in. Oh, $6.99 for the HELP o-ring kit at your local Advance Auto Parts has the o-ring you need...in fuel grade too.
