Holley 1920 diaphram return spring

I was getting near the end of a rebuild on my Holley 1920 list 3920 and noticed in the instructions a pump diaphram return spring. Mines missing it so i popped open my parts 1920 carb and its also missing it. I was wanting to know if a spring out of the Holley trick kit for the 4160/4150/2300 would work and if so what color. If not where can I get a replacement?
