So, got my 13 year old Son up this morning. We got in the woods early. Him with my 12 GA 870. Me using his youth 20 GA 870. I luv that gun, knocks the Squirrells right out of the trees. First thing right off he bags 2 of the little varmits. Took us 3 hrs to get three more for a total of five for the morning.
Get back in, clean varmitts by now its getting time to change clothes jump on the bike and haul butt to the local VFV post for they are putting on a covered bridge ride that I've promised my son we would go on.
Jump on bike with enuf time to stop for gas and register for the ride. Back bike out of the garage letting it idle while my son puts his helmet on. He says "look the bike is leaking".
Holy crap, after checking it out it appears that a nut holds the line onto the tank is gone. We scrounge the garage for a nut that fits with no luck, crap. Missed the ride.so does anyone know of the proper nut size that holds the fuel line on my 99 Ultra Classic? I believe it is 5/16ths, but I don't have the right thread pitch here.
Thx in advance

 

No,
But I bet the dealer would know.

 

Your great wealth of knowledge on this subject is awesome. I'm sure everyone appreciates your input as you make your journey thru life. I know I do.....

 

Are you talking about the nut that holds the petcock on?.....If so it is 22mm from 1975 to present. When Harley went to the Keihin carb in the mid 70s they made the switch to the 22mm petcock which is also a keihin product. Don't know what the thread pitch is though. Hope this helps a little bit.

 

It is the hex nut that holds the fuel injection line on, where it attaches to the tank. I tried 5/16th course and fine thread. As of now I'm leaning towards a metric hex nut. Will try to get a pic

 

It may still be a 22mm, but I'm not sure on the EFI. I know thats what it is on the carbed models.

 

I would have never though to check there.

There is a pic of the two fuel linesthat I found on the board. The line on the left is the one leaking and has threads sticking out the bottom. I assume it required a hex nut to tighten, if so, mine is gone

 

Looks maybe like a 3/8 or 1/4 NPT? Not sure though.
