Ok I thought they were special cause for a 94 holley carb if you look at this picture
Never to old to learn
You are correct Sal. My apologies as I thought the NPT was just a reference as I know the thread for the carb is 1/2"-20. From the cross sectio pic of the fitting, it shows a straight thread and not NPT. Did some more looking and just cannot find the correct fitting, not even from the Holley website.
