Abstract
The present invention relates to systems and methods for pressurization of a fuel line of an engine. In one embodiment, a fuel charging system for an engine is provided. The fuel charging system includes a first fuel pump in fluid communication with a fuel tank to generate a first fluid pressure within a first fuel line. The fuel charging system also includes a second fluid pump having a reciprocating piston including a low pressure end and a high pressure end. The low pressure end is in fluid communication with the first fuel pump through the first fuel line and the high pressure end is in fluid communication with an engine fuel rail through a second fuel line. The reciprocating piston is driven by the first fluid pressure to generate a second fluid pressure within the second fuel line, wherein the second fluid pressure is greater than the first fluid pressure.
