2004 Bonneville Fuel Filter(s)

Hello !
2004 Bonneville with 27,000 km showing "peeling" coating and a small bit of rust in fuel tank.Seems to run o.k.,but going to get a mechanic to clean out the tank as a preventative measure.
As this is a carbed bike,am I correct in thinking there is no new style filter in the tank with the fuel pump?I thought I read somewhere there is "gauze" style filtration in a couple of different locations:
1) Inside line in close to fuel pump
2) in petcock tube (requiring complete replacemant)
Is someone able to verify this and if possible direct me to parts required,so I can have everything accessible when it goes in for tank cleaning..
Thanks again!
Thane
