Premium Quality Remanufactured Fuel Injectors: AUS Injection offers a complete line of quality remanufactured fuel injectors for both domestic and import applications. All fuel injectors are remanufactured at our Arizona facility and undergo testing and date coding before packaging, which minimizes the possibility of defects.

All remanufactured fuel injectors that we sell come with a 1-year replacement warranty from the date of installation. We date code every unit at the time of final testing just before delivery. This process ensures that the injector was flow tested on the marked date and provides AUS with a reference date for any alleged warranties.

The Remanufacturing Process: We have identified various styles of injectors that require additional steps in the remanufacturing process. For example:

  • Multec Injectors: Additional reverse flow cleaning time
  • Bosch Nozzle type: Additional ultrasonic cleaning time
  • Delphi, Nippon Denso, Bosch pencil style: Additional reverse flow cleaning time
  • TBI Injectors: Disassembled and recalibrated In cases where part numbers are known to have external leaking problems or intermittent flow due to poor original design, they are substituted with an alternate core or a new part.

  • All injectors undergo electronic testing, where coils are checked for correct electrical resistance and weakness. Good units are disassembled, and internal ultrasonic cleaning takes place in tanks specifically designed for cleaning fuel injectors. After the internal contaminants are loosened up, the injectors undergo external cleaning and back flushing to remove any remaining dirt particles. Additionally, reverse flow pressure cleaning is carried out to remove any remaining dirt particles, especially on all GM Injectors.

    Leak Test and Spray Pattern Test: Leak testing is performed by applying pressure and maintaining it for 30 seconds to ensure there are no fuel leaks. The spray pattern is then visually inspected, and two additional measuring tests are conducted to determine if any flow differences are caused by dirt blockage or defective injector components.

    Final Steps: Depending on the original manufacturer's presentation, the injectors are either painted or polished to improve their cosmetic appearance. New replaceable components such as filter baskets, pintle caps, o-rings, and seals are assembled onto the injectors. A final test is performed with all new components installed to ensure their proper positioning and functionality. The injectors are then lubricated with special oil, and protective caps are placed on both ends to extend their shelf life.

    AUS Remanufactured Fuel Injectors: We guarantee the quality and efficiency of our remanufactured fuel injectors, and we strive to ensure that they meet the highest standards for performance and reliability.
