Turns out the hose is coming off/going to the engine, not the carb. Of course the other end could be going to the carb, but I have nothing I can find where it goes, as I said it must be this length for a reason. Carb is a rochester qjet btw.
I'll figure it out, a couple more quick questions. Where would I find the engine code ? I remember searching a decade ago and I think the numbers did not match, but I want to check again. Saw a 4 digit code under the pass side valve cover on the block, and another same location but more towards the firewall on drivers side. Also, what kind of tranny fluid is best for 1st gen birds ? I have a surplus of dexron 3 but not sure it would be a match [400 auto]
