IPC: F02M55/02
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: A fuel filtration system and methods controlling, and operating a fuel filtration system. A first fuel filter head is fluidly coupled to one or more first fuel filters, a second fuel filter head is fluidly coupled to one or more second fuel filters and a selector valve is coupled to the first fuel filter head and the second fuel filter head. The selector valve includes a primary valve inlet port, a primary valve outlet port, and a movable valve body movable from a first position to a second position. The first position fluidly couples the first fuel filter head to the primary valve outlet port and fluidly decouples the second fuel filter head from the primary valve outlet port. The second position fluidly couples the second fuel filter head to the primary valve outlet port and fluidly decouples the first fuel filter head from the primary valve outlet port.
