Abstract
A fuel system for use on an internal combustion engine has a fuel metering body which defines a fuel plenum therein. The plenum has an inlet for pressurized fuel, a pressure regulator, and a fuel outlet. Disposed within the fuel plenum, in fluid communication with one another, the inlet and the outlet, are a plurality of fuel injectors. The fuel injectors have outlets which extend through the fuel meter body and deliver fuel to the intake ports of the associated engine through flexible fuel lines terminated by pressure pulse activated poppet nozzles providing a significant degree of application flexibility. The fuel meter body mounts within the intake manifold such that fuel and electrical connections extend out of the manifold for simplified source attachment.
