I just picked up a 99 Road King Classic. Great bike and is fuel injected. I put some fuel in it and after a great test run, it started to leak out of the rear fuel line connection. There are two connections on this model. Anyway, a friend has the same set up and he advised to replace the o-rings in the top of the fittings and all should be well. When I took the rear one out it appeared that someone had put some sort of thread dope on it previously. Anyway, I found what appears to be the appropriate o-rings and put them in. Reinstalled the fittings in the tank, careful not to over tighten the fittings and crush the o-rings. I decided to service both fittings as I figured the o-rings were dry and tired. Now they both leak and worse than ever. I pulled them back out and a brass looking doohickey came out of the rear port. Is threaded and looks like it screws up into the tank and there is evidence of thread lock on it. I am wondering if this is the source of the problem? Looks like a special tool is required to put these in. There are notches opposing each other on the edges and not sure how to get them in.
Just wondering if anyone else has had this issue and how they solved the problem

Reason: Spelling
Easy fix is to replace the fuel lines with Goodridge model HDFL-005. Get the replacement o-ring kit and circlips for the injectors from Harley. The problem with the original EFI fuel lines is they have internal o-rings which are not serviceable. These will leak, and there is no way to fix them short of replacement. The reason to go with the Goodridge lines is the internal o-rings in them are serviceable. They are also cheaper and, IMHO, better looking.
