Used OEM Fuel Pumps for Trucks, Lorries & HGVs

Used truck Fuel Pumps

Fuel Pumps are a critical part of the air intake and fuel delivery system on modern trucks, lorries and HGVs. On diesel commercial vehicles they help supply fuel at the correct pressure and volume for the engine management system, injectors and common rail equipment. A high pressure fuel pump has to work accurately under heavy load, long mileage and high engine temperatures, so the correct unit is essential for reliable starting, smooth running, fuel economy and emissions control.

VRA Truckparts lists used genuine OEM Fuel Pumps removed from donor commercial vehicles, with part references and condition details shown in each product listing where available. Current stock in this category is limited and changes regularly, but examples include a used genuine BOSCH high pressure fuel pump for MAN TGX and MAN TGS applications, marked with MAN reference 51111037858 / 51.11103-7858 and BOSCH reference 0 986 437 383. This type of part may also carry a pump family reference such as CR/CP3HS3/R140/40-789S, which is valuable when matching a replacement pump to the original unit fitted to the engine.

What you will find in the Fuel Pumps category

The Fuel Pumps category is focused on used OEM diesel fuel pump parts for commercial vehicles. Because VRA Truckparts specialises in dismantled trucks, availability depends on the donor vehicles recently processed and the parts that are suitable for resale. Always check the individual listing carefully, as included fittings, pipe connections, brackets, sensors or ancillary components can vary from pump to pump.

• High pressure Fuel Pumps for common rail diesel systems, including MAN TGX and MAN TGS applications when available.
• Genuine OEM pump units removed from truck engines rather than generic universal replacement parts.
• BOSCH fuel pump assemblies with visible manufacturer labels and references where present, such as 0 986 437 383.
• MAN fuel pump references including examples such as 51111037858 and 51.11103-7858 where listed on the part.
• Euro 6 fuel delivery components for later commercial vehicle applications, subject to current stock.
• Related fittings and mounting details shown in listing photos, such as drive end layout, bolt positions, ports and housing shape.
• Used pump cores and complete pump bodies described with visible condition notes, donor vehicle information and marked part numbers where available.

Truck brands & typical applications

Fuel Pumps must be matched carefully to the exact truck, engine and fuel system. The supplied example from this category is for MAN TGX and MAN TGS Euro 6 applications, using a genuine BOSCH high pressure pump. Similar categories across commercial vehicle fuel delivery systems may include parts from European truck brands such as DAF, Mercedes-Benz, Volvo, Scania, Iveco and Renault when donor vehicles are dismantled, but compatibility must never be assumed from the brand alone.

• MAN TGX applications where the original pump reference matches the listing details.
• MAN TGS applications, particularly where the same MAN and BOSCH references are fitted.
• Euro 6 diesel engines where high pressure common rail fuel delivery is used.
• BOSCH common rail systems where the pump family, label and physical design match the original part.
• Fleet and workshop replacements where the old pump has been removed and the part number can be compared directly.

Why Fuel Pumps matter

Fuel Pumps affect far more than simply moving diesel from one part of the vehicle to another. On a modern HGV, the high pressure fuel pump forms part of a controlled injection system that must deliver consistent pressure under changing load, speed and temperature conditions. If the pump output is wrong, the engine may struggle to start, lose power, run unevenly, log fuel pressure faults or enter reduced performance mode.

Correct fuel pressure is also tied to emissions performance. Euro 6 engines rely on accurate injection control, exhaust aftertreatment and engine management calibration. Fitting the wrong Fuel Pumps, or a pump with a different pressure specification, drive arrangement or control configuration, can create faults that are difficult and expensive to diagnose. For workshops and fleet operators, matching the correct used OEM pump helps avoid repeat labour, unnecessary injector replacement and vehicle downtime.

Typical reasons to replace Fuel Pumps

Fuel Pumps are usually replaced after a confirmed diagnosis, physical damage, contamination issue or part-number mismatch. Before ordering any used pump, check the cause of failure on the vehicle, as fuel contamination or swarf in the system may damage a replacement if the wider system is not cleaned and inspected.

• Hard starting, non-starting or long cranking caused by insufficient fuel pressure.
• Engine warning lights, diagnostic fault codes or low rail pressure readings.
• Fuel leaks from the pump body, seals, pipe unions or damaged housing areas.
• Internal wear caused by high mileage, poor fuel quality or contamination in the diesel system.
• Impact damage, broken mounting lugs, damaged ports or incorrect previous installation.
• Wrong aftermarket or remanufactured unit previously fitted, causing pressure or compatibility issues.
• Damage discovered during engine replacement, fuel system overhaul or Euro 6 repair work.

How to choose the correct Fuel Pumps

Fuel Pumps are highly application-specific. A pump that looks similar may have different internal calibration, port layout, drive configuration or manufacturer coding. The safest approach is to compare the unit fitted to your vehicle with the photos and references in the listing before ordering.

• Confirm the truck make, model and generation, such as MAN TGX or MAN TGS.
• Check the engine type, engine code and Euro emissions standard, especially on Euro 6 vehicles.
• Match the OEM number stamped or labelled on your original pump, for example 51111037858 or 51.11103-7858 where applicable.
• Compare the manufacturer reference, such as BOSCH 0 986 437 383, if shown on the label.
• Check the pump family or technical marking, such as CR/CP3HS3/R140/40-789S, where visible.
• Compare the drive end, flange shape, bolt holes, mounting points and overall casing layout.
• Check fuel pipe port positions, unions, blanking plugs and any attached fittings shown in the photos.
• Review the listing condition notes for visible signs of use, corrosion, removed fittings or included components.

If you are unsure, compare the part numbers, donor vehicle details and listing photos before purchase. VRA Truckparts provides buyer guidance on how to find the right truck part and compatibility and VIN checks. Supplying the vehicle registration, VIN, engine details and the number from your original pump can help reduce the risk of ordering the wrong Fuel Pumps.

Used OEM parts from dismantled trucks

VRA Truckparts supplies used genuine OEM truck parts removed from dismantled commercial vehicles. Fuel Pumps are photographed and listed with visible references where available, including OEM numbers, manufacturer labels, pump family markings and donor vehicle details when known. Used parts may show normal signs of previous service, such as handling marks, light corrosion on external surfaces or residue around removed pipe connections. Any notable visual condition details should be checked in the individual product listing.

Parts are selected from donor vehicles, visually inspected, cleaned where appropriate, labelled and stored for resale. This process helps workshops and trade buyers source genuine replacement components without relying on guesswork or universal-fit alternatives.

Related categories

Fuel Pumps sit within the wider truck air intake and fuel delivery system. When diagnosing a fuel pressure problem, it may also be necessary to inspect injectors, fuel lines, filters, sensors, wiring, control modules and engine management components. Related items may appear across VRA Truckparts depending on current dismantling stock, but buyers should always match parts by reference rather than category name alone.

For broader help with parts identification, use trucks we dismantle to understand the types of donor vehicles VRA Truckparts works with, or use the support pages if you need help confirming a match. If the fuel pump fault is part of a wider engine repair, compare all associated components before ordering to avoid fitting a correct pump into a contaminated or damaged fuel system.
