1. Delphi EX63803AD diesel fuel injector

First is aDelphi brand product. It's never happened on any of my lists, but this time when it comes to the most disputed point, it's a rebuilt injector instead of a new one.

There are many reasons why a refurbished model has taken the lead, and we'll talk about them.

Since previously remanufactured injectors were used, most companies receive these items with a basic policy, but this is not the case with Delphi.

You guarantee that these have been completely disassembled, cleaned and inspected for possible damage or imperfections that may have occurred during use by the previous owner.

Then these errors are fixed and resolved. Once fully assembled, the injector is tested to stringent OEM specifications to ensure it is ready for consumer use.

The brand also replaces some of the older parts such as mouthpiece, screws, retaining balls and sealing rings. Replacement parts are 100% new, which means they will not be defective when they arrive.

Finally, the product itself comes with a twelve-month warranty, guaranteeing that the injector is entitled to a free exchange if it has a manufacturing defect.

This is a product that could be an excellent choice out there as it has no real downsides and has reviews that only have positive things to say about it.

2. Remanufactured GB Injector

Another refurbished injector took second place, this time from GB Remanufatura.

To beGB Refurbished Injectorsearning a better place is not only because they perform similarly or better than new ones, but buyers also prefer refurbished ones.

This may be due to the large savings that increase when the brand offers basic insurance. This product comes individually instead of in a package.

While it is recommended that all injectors be replaced at once, if one only needs to purchase one, it is good to know that there are options.

The brand itself has 30 years of experience, so you can be sure they know what they're doing. This has a base fee that is charged at the time of purchase. You have to return the old injector.

Now you will get refund amount depending on injector condition. If it's cosmetically rough, you'll get a partial refund or no money. But it reduces the initial cost.

They have been tested to ensure they meet stringent OEM specifications. You can be confident that the product you receive has been thoroughly tested under rigorous conditions. There's a reason why GB manufacturing is one of the leading brands when it comes to remanufacturing.

While this product is excellent, the fact that one of the most important parts of the installation, the O-rings, is subject to failure within a year of use could have earned it the top spot if it weren't for the point in this article.

3. HEUI Injector for Ford 7.3 Powerstroke

Third place is occupied byInjetor HEUI da Alliant Power. HEUI is the abbreviation of Hydraulic Electronic Unit Injection.

This injector, unlike the previous two options, is a completely new product. This means you don't have to worry about receiving a defective product.

But what makes this brand different is that it also has a core policy. This is odd as this policy is used by companies that remanufacture and resell injectors.

In this case, the brand guarantees that the product you receive is new. You can get up to $75 if you hand over the old one.

The manufacturer assures buyers that their injectors are of unrivaled quality and few brands can surpass them.

In this case, that number is two. Many things indicate that this product is really durable. The piston was coated with tungsten.

In addition, the brand also claims that the product has been tested according to strict OEM specifications and meets all of them. This makes the injector suitable for daily use.

Combine this with the fact that there are no issues like the original such as: B. Cracks; it also easily exceeds these specs.

There is also a two-year warranty, regardless of mileage. This means you can test your injectors to the absolute limit and no matter how hard you drive your vehicle, if it fails within that 24 month period it can be replaced.

It's no surprise that a new injector is more expensive than a remanufactured one. This is a unique product as users have had no issues with it and it should be your first choice if you want a brand new product.

4. Remanufactured Platinum Injector for 7.3L Powerstroke

Another remanufactured injector deserves fourth place in this article. Up to this point, it has become clear that users prefer refurbished ones to new ones.

They dominate this article not just for that reason, but because they are extremely good and reliable.

On the 7.3 Powerstroke I can say with certainty that some of them also outperform a new one. The brand that remodelsThese injectors are called DCP injectors.

They make sure these injectors have most parts replaced to ensure they don't have any of the original issues. The solenoid, nozzle, springs and even the o-rings are all new.

In most cases, the failure of these components affects the performance of the injector. They don't just install new components and package them. They have been tested to OEM specifications to ensure they won't fail consumers.

It also comes with a one year warranty. You can buy this product with complete peace of mind that, in the event of a defect, you are entitled to a full refund or free replacement.

If you have any doubts about purchasing a refurbished one, this warranty should put those doubts to rest. Customer support is also top notch and is offered at no additional fees.

I know this purchase is a bit risky. But it's way better than other options that claim to be the best and turn out to be the worst if I count.

If it's advertised, rest assured that you're in for some big gains in fuel efficiency and performance.

5. Boschy Gold Series Remanufactured Injector Nozzle

The manufacturer of the Boschch gold series comes in fifth and last place. Well, I don't know how these brands are naming the injectors, but one thing is for sure, platinum is certainly better than gold.

Make no mistake, this is why I chose DCP injectors over Boschch. Ooverhauled injectorsupposedly completely disassembled and then inspected.

It looks so new that if the brand wanted to sell it as new, they could. But honesty is one of the key factors in gaining lifelong customers.

Any issues with these injectors will be resolved and then all major components will be replaced. The nozzle is changed so that neither too much nor too little fuel is injected into the engine.

Seals and o-rings are also replaced to ensure no contaminants enter the injector. Without the presence of such seals, it would quickly become clogged and unusable.

After assembly, the injector is tested under stringent conditions to ensure that the consumer has no problems.

In addition, the company offers a three-year/100,000-mile warranty. This is the longest warranty in the group. So you can be assured that you will receive a free replacement for every defect for three years.

It has not been tested under OEM conditions and no one has yet purchased or at least reviewed this product. But it's better than other options on the market.

common questions

Q1 How long do the 7.3 injectors last? And how do I know they turned bad?

Well, those are two questions every vehicle owner should know, enthusiast or not. After years or decades of use, it is very common for injectors to fail. You should expect this to cause you problems as it is not designed for long-term use.

There are many ways to identify a bad injector. But you can expect it to fail around the 200,000 mile mark. You can identify faulty injectors in the following ways.

One of the reasons could be reduced fuel efficiency. The engine can also fail. The reason for this is that the injector injects too much fuel into the engine. Another reason could be that it is clogged with dirt.

Another way to identify the problem is to check the tachometer needle. If it moves up and down erratically, you have your answer. (Check out this article on 7.3 Powerstroke issues).

But if you have these symptoms, it does not mean that you have a confirmed faulty injector. It's best to have it checked by a mechanic first so you don't end up paying for an unnecessary repair.

Q2. What size and type of injectors are used on the 7.3 Powerstroke?

7.3 Powerstroke uses HEUI style injectors. It is an acronym for Hydraulically Actuated Electronic Controlled Unit Injection. This is the latest and greatest when it comes to the world of injectors. They are electronically flagged.

The 7.3 Powerstroke was manufactured from 1994 to 2003. From 1994 to 1997 the injector was a single shot 98cc AA unit.

From 1997 to 1999 the capacity was increased to 120cc, and the gun now fires split shots instead of one. Thereafter and until the end of this engine's production in 2003, the injectors were AD coded and had a capacity of 140cc.

Q3 My new injector produces smoke. What does that mean?

This depends on the type of smoke emitted by the vehicle. If the smoke is blue, the oil in the combustion chamber is burning. This happens when the sealing rings fail and oil enters the chamber with fuel.

So if the smoke is gray or blue then the problem is faulty O-rings. Separate O-rings are commercially available. Alliant Power makes excellent o-rings. You can buy them and never worry about this problem again.

If the smoke that comes out is white, the situation is much worse. That's because diesel enters the exhaust system without even entering the combustion chamber. This means that an injector was not installed correctly or is faulty.

Assuming it's not the first option, then you might be under warranty. In this case, do not hesitate to contact the brand and request a refund or replacement.

If there is also black smoke, then there is only one reason: too much fuel in the combustion chamber. You may notice smoke appearing when accelerating, but this is common.

If it can be seen during normal use, the injector is definitely defective. Too much fuel is injected into the engine.

Q4 If my injectors break, is there anything I can do to fix them myself?

Well, who doesn't like to save a trip to the mechanic and some money for it?

Well, if the mouthpiece or sealing rings are damaged, replacing them is an easy task. Do you know why it's better to get the mechanic's hands dirty than yours? If not, let me tell you.

Suppose you removed the injector and screwed something up during the parts replacement process. You are left with nothing, no spare injector, rendering your car completely useless until you get new ones.

A mechanic has experience in this area and can properly check and repair it without damaging anything. For this reason, it is recommended to spend some money and go to a mechanic.
