    I got an adapter that allows me to add a schrader valve to my TBI at the inlet. It replaces the large threaded adapter on the back of the TBI. Anyone know which one that is? (I am probably going to have to take the whole thing off anyway but it would be nice to try before taking it off...)

    YES! That's IT! It looks like #27 has larger threads than #13. thank you very much! Maybe I can do this without taking the whole unit off of the truck!

    Yes, you can do that operation without removing the TBI. If you do remove the TBI, be sure to clean the mounting surface and replace the gasket. By the way, where did you find the fitting? I've always used clamp on air conditioning service valves on the lines (used them for many years and never a leak).
    Good Luck and God Bless
