Fuel system including a self-containted flow-through pressure regulator

摘要

The present invention provides a fuel system for an internal combustion engine powered by fuel that includes a fuel tank having a wall defining a volume. The fuel system also includes a pump that is disposed proximate the fuel tank and operatively connected to the volume. The fuel system further includes piping that is coupled to the pump and is operatively connected to the internal combustion engine. A pressure regulator with a self-contained valve assembly is disposed in at least one of the pump or the piping.
