Searching for what these are using my bikes VIN and also the engine codes of a few later models. I tried searching terms like... cut hose, damper, buffer block, rubber bushing and all sorts of other stuff and have yet to find anything. Mine were so rotted, I'm guessing I mistook them for partially disintegrated fuel hoses. No bulletins either. Protective purposes I'm sure, but no mention or part numbers. Is this just an add-on? I've seen them quite a few times while searching other pump related stuff.
