Now that's a _great_ idea. Find a solenoid valve to switch the vacuum
around (I'll bet a fuel selector valve would work) and arrange it so the
solenoid has to be powered to not apply manifold vacuum to the float
bowls. Work it in so it looks like part of the regular emission
controls, add a regular kill switch for the theif to find, I'll bet _no
one_ will be able to figure out the secret without prior knowledge.
And, I don't see any reason it couldn't be added to early cars without a
canister.
