Boy, that's a tough one and I suspect something happened with the fuel pump replacement. "Very small" leaks are "very hard" to find.
You are probably not going to find it easily without a smoke machine and even with that technique, the tank is probably going to have to be dropped to fully see the smoke from any of the many pipes or the o-ring at fuel pump.
Did you use the special tool to crank the fuel pump lock ring? That ring is just insanely tough to turn off and on.
