As long as the bottom of the tank is above the float box inlet, you should be fine...gravity will take care of the rest.
If you have the height, you may consider placing it 2 feet, or so, above the flue pan so you could feed a pre-heater housed inside a steam hood.
You'll reap huge rewards in gph with those two items.
Enjoy your new toy - sounds like a really nice rig!
