Fuel Injector Line: Description and Operation
The high-pressure discharge fittings on the head of the injection pump connect to the injection nozzles with steel lines of equal length and interior
volume.
When the engine is running, the fuel is contained in the injection lines. During engine operation, a residual pressure of approximately 500 psi is
maintained in each injection line. As the injection occurs in each line, a small amount of fuel enters the line, pushing a similar amount into the nozzle at
the other end with a pressure wave.
