ATF: Bighorn - Vent and fill tubes

[TedS]

Are the vent and gravity fill tubes clamped to fittings on the fresh water tank? Or are they just pushed onto fittings or stubs on the tank?

Fresh water fill hose is banded with adjustable band clamp(radiator hose clamp) . Vents are screwed in and clamped like a water line on mine.
