ABSTRACT:
A combined fuel supply and priming system for diesel engine is disclosed. The fuel supply portion of this system may be conventional and may include a fuel supply tank, a primary fuel filter, a fuel pump, a secondary fuel filter, and a plurality of injectors for injecting diesel fuel into combustion chambers of a diesel engine. A fuel line connects these parts so that diesel fuel flows through the parts in the order named. The fuel supply system may further include a return line leading from the injectors back to the fuel supply tank. The priming portion of the system includes a manually operated primer pump, which may be connected either in line with the other parts or via a bypass connection. When the primer pump is connected in line, it may be placed between the fuel pump and the secondary fuel filter. In line connection provides a single flow path for fuel used either for priming or for normal operation. Alternatively, the primer pump may be connected to the primary fuel line via a bypass, so that the primer fuel bypasses the fuel pump. In a bypass connection, the bypass line has an upstream leg extending from the primary fuel line upstream of fuel tank and a downstream leg extending from the primer pump to the primary fuel line downstream of the fuel pump. The primer pump is operated manually. This system in universally applicable to diesel engines.
