BaitFuel Injector Kit - The BaitFuel Injector Kit allows you to fuel inject BaitFuel fish attractant into any soft plastic you fish with. Injecting the scent directly into the soft plastic adds more BaitFuel into the bait and allows it to slowly disperse from the puncture hole-increasing the amount of scent your bait releases and supercharging your baits with even more BaitFuel. 1X Injector 4X Reusable injector vials, prefilled with BaitFuel Each BaitFuel injector Kit comes with 4 reusable vials prefilled with BaitFuel.
