Internal Toroidal or External? What i mean is the standard multivalves for cylindrical tanks. you should make sure that your tanks flange where you install your multivalve is inclined 30 degrees. you can check by placing a level sensor or meter on the gas box of the multivalve it should read 30 degrees. for your toroidal tank i think it is already 30 degrees so you dont have a problem with this.
