Hi folks,

There is a small coolant hose coming off the bleeder valve on my 84 1.9.  It is hard and it needs to be replaced. It is about 6 inches long and about the size of the hose connecting the expansion and over flow tanks.
 

        Does anyone know the Internal diameter?  I’m wondering If I have the hose size.  Mainly I have fuel hose from the gas tank change out so in those diameters.  I think 11 and 7 millimeters.

        I can’t refer to Bentley so maybe someone can let me know If I have the size I need or if I need to arrange a ride to the local parts store.
