kk's woW12

i'm getting fault codes banks 1 and 2 running too lean, and it seems to happen after some thrilling acceleration... maybe dirty fuel filters or an air leak somewhere that doesn't show until there is pressure + or - applied, and does anyone know where the fuel filters are in the w12? is this in my bentley?

i just replaced two that were setting codes...they were worn through from rubbing on the engine.
