Fuel delivery system

A fuel delivery system, comprising:

• a fuel pump assembly, including:
• a pumping chamber;
• an inlet valve configured to introduce fuel into the pumping chamber;
• a piston configured to pressurize fuel in the pumping chamber;
• an electromagnetic actuator configured to move the piston;
• and
• an outlet check valve for directing pressurized fuel out of the pumping chamber;
• wherein the inlet valve is configured to be in an open position during an intake stroke of the piston to introduce fuel into the pumping chamber;
• and
• wherein the piston is configured to pressurize fuel in the pumping chamber during a pumping stroke of the piston to cause the outlet check valve to open and the inlet valve to close;
• an extension tube located downstream of the outlet check valve and the fuel pump assembly;
• a fuel pump barb positioned between the outlet check valve and the extension tube, the fuel pump barb engaging the extension tube to couple the extension tube to the fuel pump assembly;
• and
• an injection nozzle assembly including a nozzle check valve located downstream of the extension tube and the fuel pump assembly;
• wherein the fuel pump barb, the extension tube, and the nozzle check valve are configured to direct pressurized fuel received from the outlet check valve into an intake of an engine.
