Right now I'm running off of the ignition, but I just bought a early 80's VW Rabbit CIS fuel pump relay. It runs off of the tach signal, if no tach signal it will turn the pump off. Starting isn't an issue as the carbs have enough fuel in the bowls to start. Only issue would be first dry bowls start, would be easy enough to install a NO push button switch.
Relay part number 321 906 059C the one I got has a 15a fuse built right into the top of the relay.
You could do a similar thing with a generic DTDP relay and run it off the oil pressure (idiot light) switch, but it won't be as fast reacting as the Rabbit switch.
There's also an inertia switch from a Ford (IIRC), but guys say it trips every time you hit a bad bump, simple to reset.
On how I made my relay board delete engine harness go to post #150 of my engine build thread. You can get the connector from member Perry Kiel, he also makes full conversion harnesses.
Since I'm cheap I made a male connector by hacking a female connector from an old engine harness.

I did the same thing as you on my last conversion. Relay for sure on this one.. It just seems safer.
I will probably delete the board as suggested and either make my own harness or buy one from perry..
Gotta figure the regulator wiring out as well then..
Don't forget some of the CIS relays also have a built in rev limit function. Learned that the hard way going down the back straight of Mid-Ohio. Still below the red-line first time out. and I would drop power
traced it back to the relays I was using. In my setup one powered the coil one powered the fuel pump.I grabbed the relays from a my hoard of VW CIS parts from my previous Scirocco collection. Yes Ben I am back to using the term Hoard. When in Rome.
Would the starter cranking speed be enough to trigger that relay ?,my 87 GTI has what I think is the very similar relay and has the rev-limit built in with a plain rotor,comes in around 6400,some CIS Golfs have a different setup and use a rev-limiting rotor.
The setup in my Golf has a priming function to charge the fuel accumulator and the fuel distributor, the first time you turn the key ,after that the main and tank pump run up when cranking the engine,thinking this would fill my fuel bowls but I don't know what would cause the relay to prime in a carb application.
Been looking for sometime @ a safety solution and think this setup might be the go,if only I knew more about car electrics
.Yup I think I will try this..
