Hi. I need to purge my gas tank and I was wondering what the best way to do it is. I was thinking possibly disconnecting the fuel line after the pump and hooking the pump to a battery to make it run constantly and pump the tank dry, but I have no clue on how to do that or where to start. I really dont want to siphon it cause im not very good at it and i want a more thorough purge. major/time consuming work is out of the question cause ill only have 2-3 hours max to do it. Thanks.
