Thanks for responding,. This car is completely original and changing to a 4 BBL is a pretty big diversion, especially since it can be determined to be altered by the identification numbers. I did do that on a convertible car that I have however that was not so original. I'm looking into reproducing one or a suitable retrofit for now. Haven't been able to find a NOS yet. Any help appreciatedI suspect that the two barrel tube will not be a common item. Probably the only hope you will have of finding one will be a "new old stock", which will be very pricey, or a serviceable used one. I checked out a two barrel car I have, but the tube is missing.
It could be an opportune time to consider a 4bbl conversion...
my company does some 3D printing. This is a rubber hose. I've never seen a 3D printer that makes flexible stuff but that doesn't mean it doesn't exist.I wonder if a 3D printer would be an option? I don't know anything about them, but they seem to be developing a lot!
