Abstract: A connector block that directs fuel from an outer fuel line to an inner fuel line. The connector block includes an inlet that couples to the outer fuel line, an outlet that coupled to the inner fuel line, and a fuel accumulator fluidly coupled to the inlet and the outlet. The fuel accumulator directs the fuel from the inlet to the outlet.

Abstract: A modular system for injecting fuel into an engine comprises a fuel rail coupled to the engine. A plurality of connection members are coupled to the fuel rail, and each of the plurality of connection members is configured to receive fuel from the fuel rail. The fuel is directed to a plurality of fuel injectors, and the plurality of fuel injectors are configured to direct fuel to a plurality of cylinders. A plurality of outer fuel lines are coupled to the plurality of connection members, and the plurality of outer fuel lines are arranged in a single configuration. The single configuration allows the fuel rail to be coupled to a plurality of engine configurations while maintaining the plurality of outer fuel lines arranged in the single configuration.

Abstract: The present disclosure provides an enclosure or containment assembly adapted to seal a high pressure fuel rail, and an engine system including such an enclosure or containment assembly. The assembly includes two portions that can sealingly engage to form an enclosure or compartment that contains the high pressure fuel rail. Fuel line connectors leading into the enclosure to ports of the high pressure fuel rail are in a sealing engagement with the enclosure to seal the high pressure fuel rail from the atmosphere and provide an enclosed low pressure region between the high pressure fuel rail and an inner surface of the enclosure. In this way, leaked fuel can be collected from the high pressure fuel lines and contained. The collected and contained leaked fuel can be channeled to a leak detector, which can trigger an alarm with detection of a leak.
