"ta-may-to," I say "ta-mah-to." You say "six," I say "a half dozen."
You say "half empty," I say "half full." As long as we can agree to
Pull the vacuum hose off, and you got no gas. I say the vacuum is the
impetus that allows the go-go juice to flow and therefor IT is what
opens the valve. Without the introduction of the vacuum (or
turning the valve to "PRI" to force it open), the valve is an object
at rest that would prefer to remain "at rest." It's just the other
side of the same coin.
