How can I test my fuel injectors?
Keep the engine running and touch the end of a long metal screwdriver against the fuel injector. Put your ear on the opposite end of the screwdriver. A clicking sound means the injector’s working. Silence means the injector may need to be cleaned or replaced.
What is a Fuel/Diesel Injection Tester?
Your fuel diesel injector may suffer from several issues, such as leakage, nozzle chatter, or simply not being up to snuff. What you would need in that case is a fuel diesel injection tester, which can help you know exactly how well the fuel injector is working.
Fuel diesel injection testers are optimal for testing the fuel injectors for diesel engines, mechanical injectors, and off-road engines. But just how necessary is this machine in the grand scheme of things? Why should you buy a fuel diesel injection tester?
List of Top 5 Fuel/Diesel Injection Tester
VEVOR Diesel Fuel Injector Tester
The first and most notable in our list of top five diesel fuel injector testers come from VEVOR, like always.
The VEVOR Diesel Fuel Injector Tester is our first choice in diesel fuel injector testers, and it should be yours too. This high-quality product sets the bar for diesel fuel injector testers. The first notable contribution is that VEVOR comes with a heavy 0 to 600 BAR / 0 to 8000 psi dual scale gauge. This feature allows stabilizations in vibrations for the needle, making it easier to tell what value you are getting, as well as increasing the life of the gauge itself.
Next is its multifunctional tests, including an opening pressure test, an atomization test, a chattering test, and a leakage test. This diversity in testing will guarantee that you never overlook a leak. The tool kit the injection tester comes with also contains all the necessary parts and accessories to start testing immediately. Finally, VEVOR is fully functional with all types of diesel injectors, except for the Common Rail Diesel Injectors, or CRDI, so the injector tester is a little less effective on more modern diesel engines.
These features and additions, on top of others we have yet to mention, all come with a very affordable and attractive price, making VEVOR your top choice for diesel fuel injector testers! However, the items on the rest of this list are nothing to sneeze at, so keep an eye out for these worthwhile injector testers.
- Pressure Range: 60Mpa, or 600 bar
- Can Test Pressure: Greater than 35.0MPa, or 350 bar
- Fuel Tank Capacity: 4000mL
- Applicable Models: Diesel Engine Vehicle
Mophorn Diesel Injector Tester
Mophorn is a company related to VEVOR, so you can expect the same quality from them, plus some other differences.
The Mophorn 400Bar, 60000PSI Diesel Fuel Injector Tester is only somewhat weaker than VEVOR, with it not having as much of a pressure range. However, its pressure range is still excellent, and the Diesel Fuel Injector Tester possesses the same features and benefits as VEVOR, including its range of tests and wise utility.
Mophorn Diesel Fuel Injector Tester comes with a premium cast iron aluminum material for incredible durability and rigidity. On top of that, it comes with a plastic fuel cup that safely contains the fuel from the fuel injector, with Mophorn’s stainless pressure gauge accurately tracking the fuel’s air pressure. Finally, the Diesel Fuel Injector Tester is a kit that comes with other accessories, such as high pressure pipes, extra oil pipes, and a delivery valve.
All in all, Mophorn provides you a nice alternative to VEVOR, standing proudly next to their sister product.
- Pressure Range: 60Mpa, or 600 bar
- Can Test Pressure: 235.0MPa (or 550 bar)
- Fuel Tank Capacity: 4000mL
- Applicable Models: Diesel Engine Vehicle
MS Diesel Injector Nozzle Pop Tester
MS stands out from the rest for thoroughly testing their product at the MS manufacturing facility to ensure its proper performance and function. While there are not many substantial differences from the other diesel fuel injectors, MS also carries the same features as VEVOR and Mophorn.
However, you can guarantee that with the MS Diesel Injector Nozzle Pop Tester you will have a machine that can do what you need it to do most effectively.
- Material: Cast Iron, Aluminum
Nozlrater Diesel Injector Nozzle Tester
Now here is something that stands out from the crowd.
The Nozlrater Diesel Injector Nozzle Tester has a very unique and distinct form. The nozzle tester allows you to check a fuel injector for leakage, pop-of pressure, spray patterns, and chatter. Nozlrater also comes with adapters to troubleshoot nozzles used in automotive and construction engines. These issues are often overlooked when testing a fuel injector, but Nozlrater has you covered.
Nozlrater comes with a lightweight reservoir that holds 70% of a gallon of fuel so that you do not have to worry about overextending the amount of fuel you want to check. Finally, the tester is equipped with a 2-micron filter that can also be replaced at any point.
With a thorough tester, adapters for different situations, and a lightweight and easy-to-carry form for any situation, Nozlrater makes it on this list for its unique applications and usage.
NICCOO Diesel Injector Tester
The last on our list is another very powerful and durable injection tester that you should consider if you want to maximize your chances of a good test.
The NICCOO Diesel Injector Tester impresses out of the gate with a pressure and measuring range of 8,7000 psi, the greatest pressure in this list. This greater pressure allows for even more accurate testing and accuracy from the pressure valve. The Diesel Injector Tester is also simple and easy to use:
- Simply fill the oil cup and press the tester’s lever to eliminate air.
- Connect the oil tube and pull the level again.
- Finally, connect the injector nozzle with a tube and start testing your fuel and diesel properly.
With its equally impressive test variants and testing ability, and a comfortable price tag, NICCOO is a worthy diesel fuel injector tester to buy.
Different Types of Fuel/Diesel Injection Testers
There are several different types of fuel diesel injectors, such as mechanical or gasoline. In terms of testers, however, there is largely only one variation of the product, as there is only one way to test the injector, which makes it simple, at least, to buy them. Instead of listing what different types there are, we will discuss what sort of features or qualities a fuel diesel injector may have and what you should look for when you are buying a fuel diesel injection tester yourself.
What Should You Look for When Buying a Fuel/Diesel Injection Tester
The first feature you should look for when buying a fuel diesel injection tester is the pressure range of the tester. The greater the pressure range, the more accurate the injection tester valves are, meaning that you will have less of a chance of a false positive (or negative) and be able to compare the air pressure of the fuel to what the injector is supposed to have.
Next is the versatility of the tests. A fuel diesel injection tester should have multifunctional tests that check for various situations, such as atomization, chattering, and leakage. If an injection tester is incapable of testing for these scenarios, then it is functionally useless as a tester. Thankfully, most injection testers account for these tests, though some are more effective than others.
Finally, it is worth looking into the fuel tank capacity. Injection testers that can hold and account for more fuel allow for greater sample size, so to speak, and allow for more accurate testing as well.
Once you do find the fuel diesel injection tester you need, however, is it worth it?
Are Fuel/Diesel Injection Testers Worth It?
If you can get your hands on a fuel diesel injection tester, you will have found a way to keep your engines clean and identify any problems with your injector. Getting a fuel diesel injection tester will be worth it!
FAQ about Fuel/Diesel Injection Tester
1. What does the fuel diesel injection tester test for?
The fuel diesel injection tester tests the quality of the diesel injector and the fuel you intend to inject into an engine or machine.
