Where is the clicking noise coming from? Who determined that the noise is from the fuel pump? The fuel pump is rotary type so it should not emit any clicking noise, a whirring noise would be more likely.
Injectors would not produce any clicking noise that is alarming loud.
If the noise is from the engine, the most likely cause would be the hydraulic valve lash adjuster. Does the noise comes o intermittently and would go away when engine is revved?
