How to remove fuel from tank to tune for E85?

[beastmar]

I am going to have a local shop tune my car for E85. Right now I have about 3 gallons of 91 in my tank. What would be the best way of emptying my fuel?

I did some research and my plan of action would be to remove the schrader valve on the fuel rail and drain from there. But where is the fuel pump relay or fuse that I need to jump in order to have the pumps run? I found a thread posted here in the lightning forums but not one in the terminator section.

Any help is appreciated.

Any shop can make a fuel drain tune. I do it all the time.

Have a drain jug and e85 ready and just do it at the shop.
