Are you experiencing poor running conditions and are unsure if your injectors are at fault? Use the XDP Mechanical Fuel Injector Test Service to help you properly diagnose fuel injector problems rather than just "throwing parts" at your engine. With the XDP Test Service, you can test a whole set, or just a single injector in an Association of Diesel Specialists (ADS) member shop. Each fuel injector you send in is tested and inspected by a certified Bosch Master Technician. You will receive your results within 2-4 business days from the time XDP receives your injectors.

How It Works:
XDP's Injector Testing and Inspection Service is priced per fuel injector. 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.

  1. Package your injectors for shipping. Ensure they are clean and well packaged to avoid fluid leaks or shipping damage.
  2. Write your order number and "Injector Testing Service" on the outside of the shipping box.
  3. Ship your injectors to XDP using your preferred shipping method. XDP highly recommends using a trackable method and insuring your shipment.
  4. An email confirmation will be sent once XDP receives your injectors.

Testing Process:
During the first stage of the testing process, each fuel injector will be visually inspected by a certified Bosch Master Technician. After a visual inspection the injectors are then tested on a Bosch EPS-100 Test Stand with the individual tests performed below. 

  • Visual Inspection
  • Injector Test
  • Leak Test
  • Opening Pressure Test
  • Nozzle Chatter

Results & Options:
After testing is performed you will receive an email with a PDF copy of the handwritten test results with a pass or fail indication, along with the visual inspection report, and injector images (if required). From there we can return your injectors, or help you replace them. See options below. 

Option 1 - Return Injectors: XDP will return your injectors with new copper washers and o-rings for injector bodies (where required). A flat rate fee of $9.95 for return packaging and shipping applies. 
Option 2 - Purchase New Injectors: If you would like to purchase new injectors, XDP will provide you with a core credit and 10% off on your choice of any new or remanufactured injector or injector set.
