Two main non-hydraulic injector types

With cars fast becoming computers on wheels, parts that were once simple remove and refit jobs, may now require reprogramming or adapting after installation. Failure to teach the new part how to behave using a diagnostic tool can cause...

The most common problem that causes the fuel gauge to read incorrectly is a bad fuel sending unit. The fuel sending unit is used to measure the amount of fuel in the fuel tank and communicate the fuel level to the fuel gauge on the vehicle dashboard. This ensures that the driver is aware of the fuel level at all times, as well as warn when the vehicle is low on fuel, and when to visit a gas station before the tank is completely empty. If something happens to the fuel sending unit, the fuel gauge is the first to show it, so let’s take a look at how the two work together.

For smaller shops, it’s not always feasible to buy large testing equipment to check the flow rate of diesel injectors. In those cases, you can use the high voltage lead test...

Understanding how diesel injectors spray can help you understand injector diagnosis better.

Let’s take a look at how to replace an old wiring harness, or pigtail, with the new one that is supplied with your new fuel pump module.

Replacing a fuel pump can become a costly mistake if it is not the true cause of a fuel related problem.

It’s important to avoid contamination of injectors during a repair. Contamination during repairs can come from dirt around the fittings, your wrenches, your hands and many...

Non common rail technology can be broken out into three types: in line, which is sometimes called a rotary pump; an individual control pump and a unitized injection pump.

PIDs – or Parameter IDs – are important to understand when making diesel repairs. They are part of the heart of the diesel common rail and system.

Insufficient pressure and flow are an indication that a fuel pump is under-performing, but do not necessarily mean that it is failing.

Precision is key for the fuel pressure regulator on any vehicle. So when you need to pick a replacement part, choose Delphi — the brand that’s been OE engineered to perform consistently. We test our fuel pumps for performance and durability, and we use our results to make better parts. That’s why Delphi holds more than 30 OE-proprietary innovations and 150 patents in fuel module and pump design.

Ten years ago, diesel got a bad rap. But today, the Delphi common rail is earning diesel a reputation for efficiency and power. Common Rail is the fuel injection system that meets strict emission regulations. It includes a high pressure pump, injector, rail, filter and ECU. Proof that engineering a fine fuel mist, like a fine wine, gets better with time. Please visit our DNA application to check your Common Rail Injector has been repaired by a Delphi Approved Workshop using Genuine OE Delphi parts.

When it comes to building fuel modules, Delphi applies its OE expertise and technological leadership to deliver the highest level of performance and customer satisfaction. Delphi engineers each fuel module with the same stringent standards we apply to the parts we make for top vehicle manufacturers like Volkswagen and PSA.

Delphi fuel parts aren’t just high quality, they’re Delphi quality. We put over 100 years of under-the-hood experience into every part we make, so they deliver 100% satisfaction for you and your customers.
