Is it normal for injectors to make a click/ticking sound?

[Machine]

Just curious, something thats been bugging me since i got my SR Swap done. I dont really remember if the old engine's injectors clicked like that, that thing rattled all over anyway.

Edit...at least i think its the injectors, if not its something very close by. doesnt seem to be the coilpacks.

well, while we're on the topic of injectors...when i boost the smell of gas comes from the shifter (i dont have the boot or anything on), recently my FPR vac. line came off, since then its been doing that....what could it be? Im thinking injector O rings or maybe exhaust leak? I tried sniffing around the engine bay by the fuel rail but i dont smell anything or see any leaks.

fuel hose below the filter might be leaking. also if your fpr hose is off your fuel pressure is higher so at idle your probably not burning all the fuel goin in. could be reason for smelling raw fuel.

well i put the hose back on, lol (at the time)
