Ron,
Here is a picture with the single barrel 2467 Carter carburetor setup, but it's the same for the 2204 2bbl (and really for all carburetors - as it really ties into the intake manifold.)
As per the attached picture:
The inlet to the fuel pump with vacuum booster (A) comes from the intake manifold. On the 1bbl it is directly on the intake manifold (E) as the picture shows, whereas, on the 2bbl it's located on the firewall side of the carburetor/throttle body, just above the intake manifold.
The output to the vacuum wiper (F), in this picture is shown as terminated right near the fuel pump, but should run to the input of the vacuum wiper motor. I routed mine using hard line (1/8" - I think) , directly back to the fire wall, under the exhaust manifold, and up the firewall, then, used a 6" to 8" rubber hose to the wiper motor.
If you don't have a fuel pump with the vacuum booster, then you just run the vacuum line from the output of the intake manifold/throttle body to the input of the vacuum wiper motor directly. This is how it was originally done, but you're prone to loosing the wipe action while accelerating, as you loose significant vacuum with the throttle open. The vacuum assist on the fuel pump makes up for this loss of vacuum.
