    Question about S2 AVANT/SEDAN fuel tank

    Audi B4 quattro has 3 sections : one linked to the fuel neck, one that hosts the fuel pump basket and one in the front of the second.
    HOW the fuel moves from one section to the fuel pump's section ?
    I've seen some pipes linked to return pipe named in AKTE " suction pump" IS it something based on Venturi effect ?

    THanks for help !
