Abstract
A fuel delivery system for an internal combustion engine having a fuel pump with a high pressure outlet. A fuel rail defining an internal fuel chamber is fluidly connected to the fuel pump outlet. Additionally, at least two fuel injectors are fluidly connected to the fuel rail internal fuel chamber. At least one fluid check valve is fluidly positioned within the fuel rail in between two of the fuel injectors which reduces fuel pressure pulsations.
