Wet/Leaking Injector

[CJ_Derv]

Hi guys, i have recently cleaned engine bay and since have noticed that one injector nearest gearbox is wet (with diesel) and seemed to have a bubble from the injector nut when i opened bonnet the other day

Now can i just take out and nip up or do i need an replacement injector

Just took some piccies, i think i may take cheapest option and put another leak off pipe and make a new blank as this one doesnt look the best





And worst case anyone got 1 spare injector
