Pull the pump as it has a gauze filter built onto the housing, mine blocked up twice but i was running some interesting fuel!
But saying that if you cannot hear it the pump is dead, dont bother with the cheap copy ones as they dont last, i speak from bitter experience.
Assuming its a seven seater you can cut the carpet from the seat lock down channels so when its back down you cant seee the cuts, otherwise you have to strip the whole rear out.
