hey 12v98, nice bike. I'm sure your bike is injected,or it should have been fuel injected when built as the MOCO to the best of my knwledge had gotten rid of carberators by 09. technically as part of alphabet soup Harley uses its model name actually has a I at the end of the long name. aka its probably a FLHTCUI.
anyway,which basically means and FLH chassis, Ultra Classic trim with injection LOL.
if that filter you pictured is in there, I can honestly say that I have never seen anything like that before inside the tank of a Harley...
does it not have a sealed metallic can type filter inline after the electric pump?
I had a 2000 Road King and injected was an option that year. I got it injected so I could ride in the mountains without worrying about carb jets.
My 03 Electra Glide was injected too but I think all the touring models were then.
