Abstract:
1. A containment assembly for a high pressure fuel system, comprising: a first elongated portion having a first opening and adapted to receive a high pressure fuel rail having an elongated body, an inlet port, plural outlet ports, and a connecting member extending from the elongated body, said first elongated portion including a fastener portion configured to secure the connecting member of the high pressure fuel rail within the opening of the first elongated portion, a fuel inlet port adapted to sealingly engage a high pressure fuel line connector that connects to the inlet the high pressure fuel rail, and a leaked fuel drain port adapted connect to a low pressure fuel leakage drain line upstream of a leak detector; and a second portion adapted to cover and seal the first opening to form an enclosed compartment including a low pressure region between the high pressure fuel rail and inner surfaces of said compartment, said second portion including plural ports, each of said plural ports adapted to sealingly engage a respective high pressure fuel line connector including a high pressure fuel line and a low pressure passage, and to align with a high pressure outlet port of the high pressure fuel rail, wherein with the plural fuel line connectors sealingly engaged with the respective plural ports, each low pressure passage of the high pressure fuel line connectors fluidly communicates with the enclosed low pressure region.
