Rajo gave the diameters. But there is a different in length. Vendors sell the upper hose, 4", to fit '26-'27 but may need to be trimmed a bit for earlier models. Water Outlet to radiator neck dependent.
Model T
Early models (17-19) 3-1/4" long hose
Later models (19-27) had a 3-1/2" or 4" long hose,
Model A 1928-29
Short lower hoses are 1-3/4" I.D. x 3-1/2" long
Upper hose is 2" I.D. x 7-1/4" long.
