go to the auto parts store and buy 12" of SUBMERSIBLE 5/16"/8mm fuel line, the spec is SAE J30R10;
buy a new fuel filter i use WIX #33012
buy a package of JB Weld Kwik epoxy
buy a tube of Permatex Dielectric grease
do you have some Clic-R pliers? for the fuel and water lines?
get some (ebay ~$19)
have you changed the rear well nuts in your air box to rivnuts?
if you epoxy the notches in the tank flange and send me a picture i'll send you M4 rivnuts to fix the problem along with the O-rings
or you can bring your tank and air box over and i'll help you do it and show you how to replumb the internal lines so they're not such a PITA
