A 2004 Dodge Ram fuel injector is made up of a nozzle and valve though which gasoline or diesel fuel is sprayed into the engine’s internal combustion chamber. The top end of the fuel injector is affixed into an opening on the fuel rail while the nozzle outlet end of the fuel injector is affixed into an opening located in the intake manifold. An individual fuel injector supplies fuel for each individual cylinder.
