Call Bob or Brian Smith at American Diesel. They'll have what you need.

It`s a very low psi cap. Try auto suppliers, take the existing cap with you. A new cap often cures the coolant loss. AD have 2 different caps, one for the original tank system, another slightly higher psi for the later AD modified expansion tank system. About $10 from memory.
