Best way to drain fuel tank

[Milkdudd]

Hopefully I'll get a little compassion if I'm going about this completely wrong. 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. 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
