There were many tubes used in the Rochester Quadrajets over the years. Most are no longer available. All have to be identified by comparing the existing. We do not have a cross over catalog for tubes by application or carburetor number.
You can see the various tubes and dimensions in these old catalog pages. Again, this is for illustration purposes only, most of these tubes are no longer available.
Any tubes that are currently available can be found in the Quadrajet catalog here
