Hello fellow Yaris owners! I'm trying to change my fuel pump and know it's under the backseat but I can't seem to get the backseats' cushion off. The service manual says the seat should "lift up" but i've tried even putting a metal pole for leverage and cannot get the cushion to pop off. Has anyone successfully removed their back seat cushions? Is there a lock or something? It's a 2008 Yaris YR Hatch.
