A fuel injection system (10) is disclosed comprising a high pressure actuating fluid pump (332), a first plurality of hydrauli- cally-actuated unit injectors (18), and a first high pressure actuat- ing fluid manifold (334) arranged in fluid communication with each of the first plurality of unit injectors (18). The system further comprises a second plurality of hydraulically-actuated unit injec- tors (18), a second high pressure actuating fluid manifold (336) arranged in fluid communication with each of the second plurali- ty of unit injectors (18), and a device (338) for controlling Helm- holtz resonation of pressure waves between the manifolds (334, 336) and/or between the pump (332) and either manifold (334, 336). Hydraulically-actuated unit injector fuel systems, having multiple manifolds for supplying high pressure actuating fluid to the unit injectors, can establish a Helmholtz resonance effect be- tween the manifolds. The present invention controls the creation of Helmholtz resonance between the manifolds (334, 336) and al- so between the pump (332) and either manifold (334, 336).
