DFI is extremely passionate about fuel injectors. After all, it’s in our name! We get numerous questions every day from clients such as “Why are my injectors failing?” “What sets a new injector apart from a reman one?” “Can my old injectors be used as a core?”
In this post, we will be taking a close look at diesel fuel injectors and what makes them tick. All of the questions asked above and more will be answered. We are dedicated to providing you with as much information as possible when it comes time to replace your old ones. Read more below!
There isn’t just one clear answer as to why injectors fail. It is one of the questions we get asked the most. We have listed some of the most common reasons as to why injectors fail.
It is important to note that fuel injectors can mainly fail in one of two ways. Firstly, it can fail electronically. Most modern fuel injectors, except for the ISX injector, have an electronic solenoid that controls fuel flow. Unfortunately, with it being an electronic component, it is more susceptible to failure.
The second reason why an injector can fail is mechanical. Although they have various electrical components, they are still very much a mechanical part. Water, dirt, and debris can all play a part in the mechanical failure of an injector.
Are you planning some major work on your engine that requires an overhaul kit? Wondering if there is any point in adding new injectors to the list? The answer is yes. Add a set of new or reman injectors to your list today.
Over time, your diesel injectors will get worn and may need replacement. They have very tight tolerances and after countless miles, they will begin to show signs of wear.
How can you tell? It may not be obvious, but you’ll have to push that gas pedal just a little further. Alternatively, acceleration may not be what it once was. And as a result, fuel mileage drops.
Why does this happen? Simply put, the injector tip has several tiny holes to help atomize the fuel. With increased mileage, the tip itself can get clogged or the holes can become enlarged. Either option will decrease MPG’s, costing you more to operate in the long run.
It is always a good idea to replace your injectors if doing a complete in-frame or out-of-frame engine overhaul. Everything is already taken apart and easily accessible. It will save you labor and potential downtime in the future.
A HUEI or Hydraulic Electronic Unit Injector uses the engine’s oil to activate the injector. The oil gets pressurized via a hydraulic pump in the engine to make to ensure optimal pressure is achieved.
This injector type can be found on several engines including Ford, Navistar, and even some Caterpillar engines.
Want to add injectors to your list but don’t know which ones to choose? We are here to help! The general consensus is that new is always better. That may be true in certain cases, but is not necessarily when it comes to fuel injectors.
Brand new injectors (if you can find them) are extremely expensive, and will often have additional benefits when compared to their remanufactured counterparts. Companies such as DFI uses state-of-the-art machinery and practices to test and ensure each remanufactured injector performs as well, if not better than the originals.
If you buy remanufactured injectors from us, we will need a good core back. Typically, if your engine was running before taking out the old injectors, there is a 99% they will be accepted as a core. Of course, the old ones need to be the same as the ones we send out. For example, if we give you a 10R1000 we want a 10R1000 core back.
A few other basic requirements are to be met as well. Physical damage such as broken terminals means we cannot reuse that injector. Broken springs and smashed tips will also deem an old injector unusable.
To make things even easier, we even send out a pre-paid, labeled envelope for you to return the old injector cores in. DFI wants to make the process as simple as possible, so there is no wasted time.
