Fuel pump wiring
 

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.

Why? Just snake a hose in the tank and siphon out the gas. Don't make it harder than necessary.

I tried that, I pulled the fill tube right off the tank but there seems to be some sort of anti siphon plug in there you can't get a hose into it?

use a jumper wire at the fuel pump relay from terminal 30 to 87

HUMTECH, When I turn the key to position two the pump come's on then stops. Do you mean by jumping the relay it will continue to pump? Thanks

Yup, it will power the pump on. When you key on it primes the fuel system up to pressure. Once that happens pump shuts off till engine is actually running. Jumping at the relay keeps pump running

That's what I'm going to then. I will finally be able to lighten up the weight in the tank. I'm here in my garage alone so it will help not having to muscle around with all that weight. Thanks a million HUMTECH. I will follow up on my progress.

HUMTECH, That worked like a charm. The tank is completely empty, there was 18 gallon's of gas in there. Now I have another issue thrown at me. The tank strap bolt is so rusted at the strap I'm afraid it will snap when I try and wrench it off. I sprayed it with some PB Blaster and WD40 and I'm letting it soak in. I am crossing my fingers.

ALL DONE! We need a way to put SOLVED up on our threads to let everyone know we have completed the task, what do you think?
