1. An exhaust gas recirculation (“EGR”) cooler mount, comprising:
a leak off passage being positioned in the EGR cooler mount and extending fluidly between an inlet port and an outlet port, the inlet port being configured to receive fuel, the outlet port being positioned downstream of the inlet port, the outlet port being configured to distribute the fuel; a fuel supply passage being positioned in the EGR cooler mount and extending fluidly between a fuel passage inlet port and a fuel passage outlet port, the fuel passage inlet port being positioned upstream of the fuel passage outlet port, the fuel passage inlet port being configured to receive the fuel, the fuel passage outlet port being configured to provide the fuel to be combusted in an engine; an air bypass passage being positioned in the EGR cooler mount and extending fluidly between an air bypass inlet port and an air bypass outlet port, the air bypass inlet port being positioned upstream of the air bypass outlet port, the air bypass inlet port opening in from the fuel supply passage, the air bypass outlet port opening out into the leak off passage; and an air bleed check valve, when in a closed position, being positioned against the air bypass inlet port and being configured to block communication between the air bypass passage and the leak off passage, and the air bleed check valve, when in an opened position, being positioned away from the air bypass inlet port and being configured to allow communication between the air bypass passage and the leak off passage. |
