Manufactured for specific purposes, hoses and pipes are not interchangeable. Although two black rubber hoses may be the same size and have a similar appearance, they have different purposes and specifications. Substituting a similar-looking hose without ensuring it meets the required specifications virtually guarantees issues with the system and possibly even engine damage. Count on the auto part professionals at Donnelly Automotive Machine to help you find the correct replacement part.
