Prompted by a leaking radiator, I've also been replacing all the cooling hoses on the car. However, I cannot find a source for the short hose from the back of the water pump to the thermostat housing. It only has a short 'S' shape to it, as opposed to the much larger offset on the MGB GT V8 hose.
Does anybody have a part no or source for this, or know what it was originally fitted to? It seems to be different to the SD1, P5 and P6 versions.
