This Mustang Bypass Hose features a Autolite Stamping along with the C9OE-8597-D part number. This is a nice detail for any 1969, 1970, or 1972 Mustang. Please note that this hose will fit 1973 Mustangs also-the markings are just different. These bypass hoses fit Small Block V8 models only-302, 351W.
