Claims
- 1. A fuel injection system comprising:at least two fuel injectors; each fuel injector including at least one fuel inlet and at least one vapor outlet, the at least one vapor outlet being located vertically higher than the at least one fuel inlet; at least two pods, one fuel injector being inserted in each pod, respectively; each pod including a fuel inlet connection in fluid communication with the at least one fuel inlet of the injector and a fuel return connection in fluid communication with the at least one vapor outlet of the injector, the fuel return connection being located vertically higher than the fuel inlet connection; a fuel supply line connected to the fuel inlet connection of each of the pods and a fuel return line connected to the fuel return connection of each of the pods such that the pods with the injectors inserted therein are connected in a parallel arrangement.
- 2. The fuel injection system of claim 1 wherein each of the at least two injectors includes internal passageways fluidly communicating the at least one fuel inlet of the injector with the at least one vapor outlet of the injector.
- 3. The fuel injection system of claim 2 wherein an internal surface of each pod and an external surface of an injector inserted in the pod define a fluid passageway between the fuel inlet connection of the pod and the fuel return connection of the pod wherein the fluid passageway is external to the injector.
- 4. The fuel injection system of claim 1 further comprising a fuel pump connected to the fuel supply line.
- 5. The fuel injection system of claim 4 further comprising a fuel tank connected to the fuel return line.
- 6. The fuel injection system of claim 3 wherein the fluid passageway between the fuel inlet connection of the pod and the fuel return connection of the pod is generally annularly shaped.
- 7. The fuel injection system of claim 1 wherein the at least two fuel injectors are bottom feed fuel injectors.
- 8. The fuel injection system of claim 1 wherein a number of fuel inlets in each injector is four.
- 9. The fuel injection system of claim 1 wherein a number of vapor outlets in each injector is two.
