I used the pop rivet dimple dies to dimple the firewall for the auxillary fuel pump bracket. I then riveted the bracket and nutplates to the firewall. Some of the rivets I could squeeze and other had to be shot/bucked. When I stood back looking at this I realized that I had the nutplates on backwards. They need to go on the forward side of the firewall since the fuel pump will sit on the bracket on the aft side of the firewall. Bummer. I'll have to drill this out tomorrow and swap the nutplates around to the other side.
