Injector cleaning and flow testing is what we do and we do it well.

Why pay 4 – 16 times or even more for a new injector or, at minimum, double the amount for remanufactured ones if, for as little as $18.00 per manifold or $25.00 per direct injector, you can have your gummed up, clogged, dirty or leaking  injectors restored to their original condition.  Our fast, reliable and cost effective OEM approved ultrasonic cleaning process and flow testing will save you money.

Call 1 800-381-2065

(Monday – Friday: 8:00 AM – 6:00 PM, Saturdays: 8:00 AM – 4: PM (Central Standard Time)

We will return your injectors within 24 – 48 hours after we have received them.

We do not take your business for granted. We are more than willing to earn it, therefore  we guarantee our work and if we cannot restore  your fuel injectors to function like new, we will not charge you for the time spent on those injectors we were unable to clean !

Ultrasonic Fuel injector cleaning and flow testing services

The electronic fuel injection systems used in conjunction with today’s engines, may it be automotive, motorcycle, marine or industrial, are sophisticated and very reliable. They must and can adapt to a wide range of conditions and their real-world performance often comes down to the accuracy and consistency of the injectors used. Each injector has to deliver exactly the right amount of fuel when required to do so. Has only milliseconds to do so and not only must it deliver the exact quantity of fuel but it must do so without changing the spray pattern. Regardless of condition it must be able to repeat this process thousands of times year in and year out. Sometimes in the most adverse conditions known to man. If it cannot do so engine performance will suffer.

To maintain this kind of performance it is of the utmost importance that fuel systems are kept as clean as possible. On newer engines this can be achieved by using quality gas and the occasional use of a good fuel injection system cleaner but once injector problems start to appear the only reliable and guaranteed way to deal with the problem is ultrasonic cleaning.

Cleaning injectors outside the engine with the proper cleaning equipment is the only cleaning method that guarantees your injectors will operate like new. No other cleaning method can and will give you such guarantee.

The ultrasonic cleaning and flow testing procedures we follow as well as the equipment we use is approved by the largest fuel injector manufacturer in the world.

We don’t just do injector cleaning we understand fuel injection systems and the way they function. Give us a call and let us help you with your injector problems. We like helping and talking too our customers.

Injector Cleaning:

spray pattern variationWith our manufacturer approved  cleaning process and specialized computer controlled testing equipment, we can restore most dirty, clogged or leaking fuel injectors to operate at the same level and standard as that of a new one.

After all, reconditioned or remanufactured fuel injectors are a used, injector that has been ultrasonically cleaned, flow tested and fitted with new O-rings, filter baskets and pintle caps.

Ohm Testing:

OHM Test Fuel InjectorsUpon arrival the  injectors are Ohm tested for resistance. Those failing the resistance test are set aside and will not be cleaned because they are deemed to be irreparable.

We do not charge for any of the diagnostics we performed on injectors that are not serviceable.

Now the injectors are externally cleaned and then inspected for external damage. Injectors with visual cracks and exposed coil windings are rejected and will not be serviced and cannot be reused because they could pose a fire hazard. The injectors are now numbered and they are ready for the next step.

Injector diagnostic and testing equipment:

ultrasonic fuel injector cleaning and testing equipmentThe injectors are now installed in our computer controlled testing machine where they are tested for reluctance. If they fail the reluctance test they are deemed irreparable.

Under operating pressure, usually 43 psi /3 bar, the injectors are visually checked for pintle, ball or disc seat leaks. Spray patterns are checked for atomization and distribution and finally a flow test is done to determine the amount of fuel delivered.

GDI or direct injectors are tested at 73.5 PSI (5 bars) only. This procedure is also factory approved and done at lower than operating pressure due to the dangers involved with testing at high pressure.

The ultrasonic cleaning process:

ultrasonic cleaning injectorsWhere applicable components such as O-rings, filter baskets and pintle caps are removed. The  injectors are now placed in an ultrasonic bath containing a hot biodegradable environmentally friendly cleaning fluid.

Whilst the injectors are opened and closed at various speeds for approximately 25,000 – 30,000 times the cleaning fluid enters the injector nozzle and in conjunction with the ultrasonic sound waves start to break loose the dirt inside of them. Once this process is completed the injectors are back flushed to remove all traces of dirt and contaminants.

Final flow Testing:

The cleaned injectors are now re-installed in the  flow bench where they are once again checked for leaks. After the leak test the injectors are tested for atomization and distribution. Then by means of dynamic flow testing volume is tested under various rpm. Finally a static flow test is perform.

Once all the required tests are passed, new O-rings, filter baskets and pintle caps are installed if and when available. The cleaning process is now complete and the reconditioned  injectors are lubricated and placed in a plastic bag. A comprehensive report is prepared for the owner and included.

Note: We don’t easily give up on leaking injectors or the ones that prove difficult to clean. In most instances we will keep on trying until the injectors work the way they should. We will not charge you for the extra time spent and if we are unsuccessful we will not charge you at all.

Faulty fuel injectors:

Faulty fuel injectors will cause check engine light to displayFaulty injectors may it be gummed up, clogged, leaking or dirty have the potential to cause expensive and catastrophic engine failure. Proper maintenance will help you avoid these costly repairs.  Injector cleaning should always be considerate as part of you maintenance plan especially on older engines.
