After takeoff I accomplished the climb checklist; we noticed that the #1 Aux pump light didn't extinguish. I cycled the #1 Aux pump switch on and off to try and get the problem resolved; we were unable to get the light to extinguish. I notified ATC and contacted Company Operations to notify them of the issue. Shortly after we noticed that we had significantly less fuel on the #1 main tank; and it was dropping rapidly. The Captain declared an emergency with ATC and we returned. When time permitted I advised the Flight Attendant and passengers of the situation at hand and that we were returning. During the flight; after we had declared an emergency; the #1 Aux pump light went out and it appeared that we had stopped losing fuel.
