How to test fuel pump? How to attach pressure gauge?

I just looked in my 69 Service manual. It said to disconnect fuel line prior to carb, place that fuel line in a bottle (didn't say which size), disconnect coil wire and crank engine with starter. The fuel pump should pump out one quart in 60 seconds. Since I assume the fuel amount would be at a steady rate, perhaps you could also assume that 16 ounces in 30 seconds would also be satisfactory. This might not be the most accurate test, but it should give you a ballpark idea of whether the pump was working OK. It did not mention anything about engine size.
