| I was hoping for a good critique so I could learn something more from this attempt. You're right about the TB nipple not being part of the sealed vacuum system, but my car runs and idles fine with the vacuum line from the TB to the balance tube in place. I will try with the nipples capped and see if I can "feel" a difference. Better yet, I will get a vacuum gauge and report any differences with the lines connected different ways. I also am not as sure how "precise" the original vacuum connections to the canister were, given the various stages of condition and wear to these aging filters. I feel better knowing that all the connections to the system were either eliminated or made new. There seems to be two main schools of thought about altering emissions systems. The "conservatives" who feel that everything must be left as stock as possible or "there is always a price to be paid," and the "radicals" who feel that everything that doesn't contribute directly to making horsepower should be ripped out, lol. I guess I'm a moderate. I believe that the effect of properly removing or altering emissions equipment can be a good one. The emissions systems are designed by the automotive engineers to be compromises to federally mandated laws. Before these laws, cars ran great without all these extra lines and systems, but were unfortunately gross polluters. I also feel the car enthusiasts' contribution to air pollution by modifying these systems is negligible, so I don't have a philosophical objection either, even though these modifications are technically illegal. Can you offer a suggestion the way you would finish off the vacuum lines under the hood? Would you simply cap them?
