XDP Fuel Injector Testing and Inspection Service

Posted on by

Diesel Injector

Properly functioning fuel injectors are essential to getting the maximum performance and fuel mileage out of your diesel engine. If your truck is experiencing a recent loss of power or decreased MPG’s, consider having your fuel injectors professionally tested. XDP now offers in-house Diesel Fuel Injector Testing and Inspection, as well as an Ultrasonic Fuel Injector Line Cleaning Service.

Deposits can build up in the tips of fuel injectors which severely restricts flow. Your injectors can also get tired over time. Eventually, they can wear down and even develop cracks. Unfortunately no injector cleaner or fuel additive is going to be able to fix a worn/cracked injector. XDP can help properly diagnose your fuel injectors. Stop firing the parts cannon at your engine and wasting your hard-earned money on the wrong parts.

Send a complete set, or just a single injector to be tested. Each fuel injector you send is tested and inspected by a certified Bosch Master Technician. You will receive your detailed results within 2-4 business days from the time XDP receives your injectors.

Testing and Inspection Procedure

The XDP Fuel Injector Testing Service is intended to provide you with a complete diagnosis of the fuel injectors in your diesel engine. The test procedures outlined below cover a wide range of functions and give you definitive answers to the current condition of your fuel injectors. 
Visual Inspection 
A visual inspection is the first test that is performed when your injectors are tested by XDP. The trained eye of an experienced technician can find issues such as injector body damage, damage to the injector nozzle, or components damaged from contaminated fuel, excessive heat damage, and many other conditions. 
Injector Test 
An Injector test refers to the basic tests performed to ensure that a fuel injector is working properly. Functions like nozzle spray pattern and obvious signs of leakage are first noted during the initial analysis. 

Leak Test 
On the Bosch Test Stand, there are two leak tests performed. Each series of tests are performed to detect if any leaks are present.  
The first test builds up to a pressure just beyond the bias pressure of the injector nozzle. This test indicates the following.  

  • The nozzle spring can keep the nozzle closed 
  • The needle is not stuck in the open position 
  • There is no debris trapped between the nozzle needle and nozzle seat. 

The second test increases pressure all the way to the maximum operating rail pressure. This test indicates the following.  

  • There are no external leaks 
  • There are no cracks in the injector body 
  • The injector nozzle does not leak 
  • No excessive internal leakage

Ultrasonic Fuel Injector Line Cleaning Service XD912

XDP can also help prolong the service life of your fuel injector lines with our Ultrasonic Injector Line Cleaning Service. Injector Lines are often damaged or filled with debris, especially when an injector has failed due to fuel contamination.

It is a little more complex to thoroughly clean the injector lines than most people realize. Spraying brake cleaner in the lines and blowing them out with compressed air usually isn’t enough. While there are good intentions in cleaning them yourself, without the proper tools and experience the injector lines may never be completely clean. Using an Ultrasonic cleaner, XDP’s Fuel Injector Line Cleaning Service removes debris and contaminants from your injector lines and helps eliminate the risk of contaminating your fuel injectors.

How It Works

XDP’s Fuel Injector Testing and Injector Line Cleaning is priced per fuel injector/line. Simply add the quantity to be tested to the cart, check out, and then proceed with the steps below. Each test is priced individually, per injector/line.

  • Package your injectors/lines for shipping. Ensure they are clean and well packaged to avoid fluid leaks or shipping damage.
  • Write your order number and “Injector Testing Service” or “Fuel Injector Line Cleaning Service” on the outside of the shipping box.
  • Ship your injectors to XDP using your preferred shipping method. It is highly recommended that you use a trackable method and insure your shipment.
  • An email confirmation will be sent once XDP receives your injectors.
