By the way, you have two fuel pumps: one in tank pump fed via fuse 11 and the one you have replaced, underneath the car. This is not fed via 11, but directly from the fuel pump relay.
The fuel pump relay is actually a dual relay and a fuel injection relay unit would be a better name for it. One of its relays is fed via the ignition key and switches the ignition on and off. The other is controlled from the ECU and switches both fuel pumps on and off. Clicking is therefore no indication that the fuel pump relay is working properly!

Thanks. I was under the impression clicking meant it was working.
