Gen 1 Hayabusa fuel tank question.

[Apollonick]

If anyone can point me in the right direction I'm helping fix a gen 1 Hayabusa that's modified it seems but if someone knows where some of these wires and hoses lead to and could answer below would be greatly appreciated the info I'm finding isn't applying lol. First picture is a small metal line coming from the back of the tank near where the seat goes. 2nd is the fuel filter and pump and wires 3rd is all the wires and connections going into airbox.

man?
hell - in what dusty area did you leave that bike and how long?

to me it looks like a bad guy had emptied his wheat-mill-powderbag under your tank.
before starting any other action please clean first deeply.

and while cleaning download the manual and its extensions til 2002 for the gen1 here by this link.
microfiches can help when surching spare parts by original numbers.
the owners manual is only nice 2 have but without any deeper sense, if you have the main manual ´99-´02
