A fuel system is disclosed which comprises a fuel pump, a spill valve and an injector provided in a single unit. The injector includes a valve member biased towards a seating by a coiled compression spring. The spring is engaged between a spring abutment of the valve member and a piston. The piston is arranged such that the face thereof facing away from the spring has fuel applied thereto when the spill valve is opened in order to assist movement of the valve member into engagement with the seating.
