Used Truck Fuel Injectors & Controls, Pipes & Injector Parts

Used truck Fuel Injectors & Controls

Fuel Injectors & Controls are critical parts of the diesel air intake and fuel delivery system on modern trucks, lorries and HGVs. The injector has to meter fuel precisely into the cylinder at very high pressure, while the surrounding control parts, pressure pipes, inlet connectors and retaining hardware must keep the system sealed, correctly aligned and secure under heavy commercial vehicle operating conditions. On a truck engine, a small mismatch in injector type, pipe shape or connector reference can affect starting, running quality, fuel economy, emissions and long-term engine protection.

At VRA Truckparts, this Fuel Injectors & Controls category is focused on genuine used OEM truck parts removed from donor commercial vehicles. Current and recent examples include MAN TGX and MAN TGS fuel injector parts, a Bosch fuel injector with references such as MAN 51101006169 and Bosch 0445120341, a MAN fuel injector pressure pipe with references 51103040635, 51.10304-0635 and 51103016404, a MAN injector clamp / hold-down bracket 51101040065, and a Bosch injector inlet connector / high-pressure connector F00RJ02047. Stock changes as vehicles are dismantled, so always check each listing for the actual part shown, the available OEM numbers, condition notes and vehicle information.

What you will find in the Fuel Injectors & Controls category

This category may include the injector itself as well as the surrounding components needed to secure, feed and connect the injector within the high-pressure diesel system. Availability depends on the donor trucks currently being dismantled, so the items listed may vary from individual injectors through to pipework and smaller retaining components.

• Used OEM diesel fuel injectors for heavy commercial vehicle engines, including Bosch injectors where shown in the listing.
• Injector pressure pipes and diesel injection lines, such as rigid steel high-pressure fuel pipes for MAN TGX and MAN TGS applications.
• Injector clamps and hold-down brackets used to retain the injector securely in the cylinder head.
• Fixing bolts and mounting hardware where included with the used injector clamp or bracket listing.
• Injector inlet connectors and high-pressure connectors, including Bosch references such as F00RJ02047 when available.
• MAN OEM fuel delivery references such as 51103040635, 51.10304-0635, 51103016404, 51101040065 and 51101006169 where matched to the item.
• Related fuel delivery control parts that sit close to the injector assembly and must be matched by number, shape and connection type.

Truck brands & typical applications

The examples currently associated with this Fuel Injectors & Controls category are mainly for MAN commercial vehicles, especially MAN TGX, TGS, TGL and TGM model ranges. Some listings cover MAN TGL, TGM, TGS and TGX vehicles from around 2005-2021, but this must not be treated as universal compatibility. MAN part numbers can vary by engine, power output, emissions specification and production date, and Bosch injector numbers are often just as important as the vehicle model description.

• MAN TGX injector parts, pressure pipes, inlet connectors and Bosch fuel injector references.
• MAN TGS diesel injector components and high-pressure fuel delivery parts.
• MAN TGL and TGM injector clamps or hold-down brackets where listed by part number.
• Bosch-equipped diesel systems using specific injector and connector references, not generic visual matching alone.
• European HGV and lorry applications where the part number, donor vehicle information and physical layout confirm suitability.

Why Fuel Injectors & Controls matters

Fuel Injectors & Controls directly influence combustion quality. A correctly matched injector delivers the right quantity of diesel at the right moment and spray pattern, while the pressure pipe and inlet connector must carry fuel safely without leakage or distortion. The clamp or hold-down bracket is also important: if an injector is not secured correctly, it can move in the cylinder head, damage sealing surfaces, create blow-by, cause poor running or lead to expensive follow-on faults.

On modern HGV diesel engines, fuel injection parts also work alongside engine management, emissions control and high-pressure common rail systems. For workshops and fleet operators, downtime caused by an incorrect injector, damaged high-pressure connector or wrong pipe shape can be costly. Choosing a genuine used OEM part with a matching reference is often the most practical route when repairing a truck that needs to return to service without fitting a random aftermarket part of uncertain specification.

Typical reasons to replace Fuel Injectors & Controls

• Injector failure causing rough running, misfire, poor starting, excessive smoke or uneven idle.
• Incorrect fuelling symptoms after diagnostic checks point towards a specific injector or fuel delivery component.
• Damaged injector body, electrical connection or high-pressure inlet connector during removal or previous repair work.
• Leaking or corroded injector pressure pipe, diesel injection line or sealing area.
• Rounded, cracked, missing or incorrectly fitted injector clamp / hold-down bracket.
• Surface corrosion, impact damage or distortion on pipework that prevents safe refitting.
• Previous non-OEM, wrong-number or incompatible replacement part fitted to the truck.

How to choose the correct Fuel Injectors & Controls

Fuel injection parts are reference-sensitive. A part that looks similar may not be suitable if the injector calibration, Bosch number, pipe bend, connector length, thread, clamp shape or mounting position is different. Before ordering used Fuel Injectors & Controls, compare the details from your old component against the listing photographs and description.

• Confirm the truck make and model, such as MAN TGX, TGS, TGL or TGM.
• Check the engine type, engine code, power rating and Euro emissions standard where available.
• Match the OEM number, for example MAN 51101006169, 51103040635 or 51101040065 where relevant.
• Match the Bosch or supplier number, such as 0445120341 or F00RJ02047 when shown.
• Compare the pipe shape, connector type, threads, sealing faces and high-pressure union layout.
• Check whether the listing is for the injector, pressure pipe, clamp, inlet connector or a related control component.
• Look carefully at mounting points, included bolts, bracket style and visible condition in the photos.
• Use donor vehicle details and part references rather than model name alone.

If you are unsure, compare your existing part with the listing images and use the available reference numbers before placing an order. Our guides on how to find the right truck part and compatibility and VIN checks can help workshops, trade buyers and fleet maintenance teams reduce the risk of ordering the wrong component.

Used OEM parts from dismantled trucks

The used Fuel Injectors & Controls listed by VRA Truckparts are removed from donor trucks and commercial vehicles during the dismantling process. Parts are identified, photographed and listed with visible reference numbers where available. Listings normally show the actual used part supplied, so buyers can inspect the injector body, pipe ends, clamp shape, connector design, bolt inclusion and general condition before ordering.

Used diesel fuel system parts may show normal signs of previous service, such as cosmetic wear, surface marks, handling marks or light corrosion on external steel components. This is expected with genuine used HGV parts. Where a listing includes specific condition notes, prior checks or donor vehicle details, those notes should be read alongside the photos. You can also read more about our dismantling and quality process to understand how parts are handled from donor vehicle to storage.

Related categories and fuel system buying support

Fuel Injectors & Controls sit within the wider air intake and fuel delivery area of a truck. When diagnosing a running issue, workshops may also need to inspect connected fuel pipes, air intake components, engine sensors, wiring plugs, mounting hardware and related engine parts. Because stock changes as trucks are dismantled, related items may appear in other sections of the VRA Truckparts catalogue depending on what is available at the time.

For help choosing correctly, start with the part number stamped on the existing component, then compare the listing photos and references. If the number is missing or damaged, the vehicle registration, VIN, engine details and photos of the old part can help with identification. Our trucks we dismantle page is useful for understanding the types of donor vehicles that may supply used OEM HGV parts.
