I assume the issue is the welded in wire that is present in the F.I. type tanks that keep a fuel nozzle from basically entering the tank. If you have a F.I. tank it should be simple enough to remove the tank, remove the hatch to the fuel pump and nip that sucker out with a decent set of cut pliers, or it least would seem that way to me. That wire can only have a purpose as to keep the fuel nozzle from contact with the pump assembly, what else would it accomplish other than that? Even if it's present on a carbed bike tank, again they make nippers that one could remove the offending wire from the outside, I would just cut one side and bend it down and out of the way. Or is there some issue here I'm not seeing? Feel free to enlighten me. As a disclaimer, if anyone should remove that obstruction, it would be that individuals responsibility to always have the presence of mind to not be bumping into their fuel pump assembly when gassing up. My inner Lawyer told me to add that.
