Tank pressure in either case will be high, just run the gas through the correct regulator to get the service pressure needed. I guess there would be a regulator on the tank, so you should check what pressure that puts out. My KAB6 uses a 30psi regulator. My regular turkey fryer uses a 10psi regulator. The air intakes on that burner are huge, you'll need to close them significantly to get a good flame.
