I would have to say intank is the best method too, but if that's not an option, its really hard to beat a nicely sumped tank. I can drive my 71 with factory in cab sumped tank on E for a long time and never get any starvation problems. They do have their drawbacks, changing the pump or filter could be messy if the tank is full, but for no more than I do that I'll deal with it.
