99 Alero Fuel Pump

I Have a 99 Alero and I Blew Up The Motor #4 Rod When through the block. Well I still have about 3 Gallons of Fuel in the tank I want to get the fuel out before I scrap the car I want to do this the easy way I could care less about destroying anything because its Junk so I was thinking of finding a way to make the fuel pump run continuously then taking the fuel return line off and hooking up a rubber hose into a fuel can. how can I make the pump run continuously? I Was thinking of just putting 12 Volts to the relay. Would This Work?
