Fuel pump with actuator 1003815133, aftermarket

Fuel pump with actuator 1003815133 is an aftermarket part for the construction machines. According to the product card, the pump comes complete with its actuator.

The plungers, rotors and valves inside the pump, working thousands of times a minute, are made with clearances of a few microns. The pump is therefore opened only in a clean room, and its internal settings are made in a fuel injection workshop with a test bench, where its delivery, timing and pressures are measured. These values are needed for the engine to give its rated power and meet emission limits. Field adjustments to the pump can make the engine overheat and its parts wear early. The pump setting is only changed in a competent workshop. The label on the pump is kept, as it is used to confirm the part number.
