Thanks RS 2000 - yeah I do mean fuel tank vapor line (thanks for correcting my terminology).
Sounds to me like there is no really easy way for me to hook up the last line on the canister, in an effort to leave it there.
As per your suggestion, I am going from the ported vacuum (on the bottom of the carby), to the outer connection of the vac advance. I don't have any vacuum switches, but I do have the vaccum tree on the thermo housing, and the vacuum connection on the manifold. Would I be going backwards if I hooked it up to these?.
Or perhaps just straight to the manifold vacuum (in an effort to hook it up to "something" to make it "look" like its in use) - without affecting performance?.
