Rich OE legacy
Our heritage dates back to the legendary CAV brand, and the introduction of in-line and the iconic DPA pump – the best-selling rotary pump worldwide. Both were revolutionary for their time, setting new standards for reliability and power, and we’ve continued to push the boundaries ever since.
Three choices for fleets
By providing three choices – new, reman and repair – we can provide fleet managers with convenient service and maintenance at a very competitive cost.
Latest generation OE technology
Our latest generation F3 system takes engines beyond the 2021 global emissions and fuel economy regulations and through the next decade. Based on our proven Euro VI Common Rail technology and capable of 3,000 bar injection pressure, it delivers a substantial improvement in emissions, fuel economy and refinement for the lifetime of the engine.
OE-approved repair
In addition to new and remanufactured units, we also offer authorised repair through our global network of Delphi Diesel Centres. Replacing all wearable and performance critical parts, with like-for-like OE, and using OE-approved test plans and equipment, it offers a quality but economical solution.

Reman
For an equally fast, yet more cost-effective turnaround we offer a range of remanufactured parts. Available off-the-shelf, typically within one to two years of vehicle launch, they are built using OE parts, equipment and processes, and are calibrated to exacting OE specifications.
OE expertise in the aftermarket
Of course, we’re committed to supporting these technologies in the aftermarket. We offer a range of new OE components, identical to those originally fitted, including our pioneering Electronic Unit Injector, Electronic Unit Pump, Smart injector and Multec® Common Rail.
Commercial vehicle diagnostics and test
Our dedicated diagnostic solution for trucks, buses and trailers, supports the key commercial vehicle manufacturers and systems, including the ability to carry out dosing tests, Adblue freeze monitoring calibration, system drain down and regeneration of the SCR system. We also offer a range of OE-approved test equipment for quick and accurate test and repair of the latest heavy duty applications.
Training from the OE experts
Designed to help you prepare for the very latest heavy duty diesel fuel injection technologies, our extensive training programme covers the repair of key systems, including Electronic Unit Injector and Pump and Smart injectors. Learn more about our training.

Resource Highlights
Worried about non-starts or injector faults after fitting new diesel components? Contamination and trapped air are often the cause – and they’re easy to overlook. In this video, our Delphi expert, Phil, takes you through common post-installation issues and how to avoid them.
- Identify damage inside injectors caused by air or debris
- Avoid contamination during injector installation
- Understand different pump types and how they affect bleeding procedures
- Use diagnostic routines or manual methods to bleed air, depending on system setup
- Safely crank and prime the fuel system to ensure smooth starting
- Use the Delphi HD3000 to bleed systems with HPV components
What are the most common injector problems?
There are two main culprits: contamination and air in the system. Contamination damages delicate parts while air prevents proper lubrication, leading to sticking nozzles or failing control valves.
How can I avoid contamination during injector installation?
Keep protective caps on until the injector is about to go into the engine. Exposing the inlet, nozzle, or back-leak ports – even briefly – can allow dirt in and cause damage before you’ve even started the engine.
What is the best way to bleed air from the system?
That depends on the vehicle and fuel system. Some setups allow you to run the in-tank pump via diagnostics. Others require a manual primer. If your vehicle uses a high pressure valve (HPV), you can use the Delphi HD3000 tool to open up the system and purge air efficiently.
What if the system doesn’t have a high pressure valve?
If there’s no HPV, you’ll need to crack open the injector pipes slightly, crank the engine to bleed fuel through, then tighten and torque correctly once fuel appears.
Do I need to worry about electrical connectors when bleeding?
Yes – always keep electrical connectors plugged in. Without a seal, leaking fuel could enter the solenoid and damage the injector beyond repair.
