| Bosch Part Number | 3 418 301 003 |
| Full Series Designation | 3 418 XXX XXX (Part of the series for Plungers and Barrels) |
| Component Type | Plunger and Barrel Assembly (Pump Element) |
| Primary Application | Bosch PFR Pumps (Fixed Registration Pump – Single-Cylinder Unit Pump) |
| OEM Linkages | Commonly used in engines by: SAME, Lamborghini (older tractor/agricultural engines), VM Motori, Hatz. |
| Critical Function (1) | High-Pressure Generation: The plunger moves inside the barrel to create the extremely high pressure necessary to open the nozzle and inject the fuel. |
| Critical Function (2) | Metering: The amount of fuel injected is regulated by rotating the plunger. The plunger features a helical groove that changes the effective stroke, thereby controlling fuel dosage. |
| Service Aspect (1) | Matched Pair: The plunger and barrel are manufactured, ground, and calibrated as a single, unique pair. They must never be replaced individually but only as a complete set. |
| Service Aspect (2) | Manufacturing Quality: The plunger operates within an extremely tight clearance (tolerance, in the micrometre range) inside the barrel to maintain pressure. Any contamination or corrosion drastically reduces its efficiency. |
| Installation | Installed directly into the body of the high-pressure pump (PFR pump unit), often secured from above by the delivery valve (such as the 1 418 502 013). |
| Stamping/Marking | This element often carries the embossed reference: 3301-003 (Referring to the pump designation: EPF3.301.003). |
