Draining gas tank

[Milkdudd]

I've done some searches here and can't find out the preferred method of draining the gas tank. I've found several ways watching YouTube videos and such but there must be one preferred go to method. Ideally I'd find a way to get past the anti-siphon mechanism even if it means buying some stuff to do it. If that wouldn't work I'm thinking of hooking a tube to the fuel pump outlet under the back seat and jumping the relay contacts. Does that make sense? As a retired guy I drive very little, basically nice days in the summer. That said this is not likely the last time I will need to do this so if anyone knows the best way to go about this I would appreciate any and all advice. Thanks
