The 275 Series Electric Actuator is a second-generation design more powerful than its predecessor. It is for Bosch style P 3000–7000 fuel-injected pumps. Coupling the 275 Series with a fuel pump results in a high-performance fuel control system without external linkages or brackets. Its two isolated chambers eliminate the possibility of any magnetic particles collecting and jamming the actuator. As a result, the 275 Series typically outlasts the life of a diesel engine and is maintenance-free. Camshaft bearing retainer kits, position feedback transducers, and heavy-duty bearing retention options are available.
