I decided to let the pump drain my fuel tank since it still works but i'm not sure where to put the hot and ground. I don't want to fry the pump cause it's my last resort to drain the tank. I put a drain tube on the discharge end of the fuel filter, but when I turn the key on it only pumps for a second then stop's. Now I need to pull the plug from the pump and hot wire it to run constant till the tank is empty. The wires to the pump are:
Big Grey or white
Big Black
Small Purple
Small Black
Hoping there's a Tech out here that knows which terminal I need to jump. I'm getting desperate. Thanks for any suggestion's.

 

Well, problem solved. Jumped the relay and let the pump run until tank was empty.
