Andy unless you have excessive pressure in your cooling system (due to a blowing head gasket) you shouldn't ever have steam coming out of that hose . . . . so if it's not a BHG it may be the Radiator Cap as has already been suggested.

It is a special dual design, as when cooling down it opens to allow coolant to be sucked out of the overflow tank back into the radiator (if it needs it) . . as well as of course acting as a safety valve and opening if excessive pressure builds up

By the way, have you not found the UK Mk3 Supra Forum?
