Topic: Exhaust air check valves

[Jeff1967]

I am looking for replacement hoses for the exhaust air check valves on my 67. The hoses connect to valves on each side of the block above the exhaust manifolds which tee's at the front of the engine, the other portion of hose runs back and connects to the anti backfire valve by the firewall. I want to find the original replacement hose material that is not smooth walled but rather has the black textured style. Can anyone recommend a parts house that stocks that type of hose?

Thanks

The only source that I found was used hoses. Try junk yards. Almost any 67 or 68, Ford or Mercury small block (289 and 302) should have them.
