Fuel Rail: Description and Operation
Fuel Rail (Delivery Pipe) W/Injectors Attached For Testing
The fuel rail is a reservoir which supplies fuel to the injectors at equal pressure. Its volume is larger than that of a fuel hose or tube so that when one
injector opens, it doesn't cause a pressure drop in the fuel supplied to other injectors.
