Don't Waste Money on New Fuel Injectors

Injector Masters, here to help with next day service.


Using the newest and best available technology and a decade of expertise, Injector Masters saves you money by completely cleaning and back-flushing your present injectors to eliminate the contaminants that cause them to become restricted and leak.


We clean and rebuild your injectors for a small fraction of the price of replacement injectors.


When you get them back the next day, simply reinstall them, and keep accumulating miles and run hours.

Injector Repairs

Most injector-related issues are brought on by poor fuel quality and/or fuel system neglect. Over an extended period of time, this may cause injectors to stick. Fuel additives and treatments do not effectively back-flush and clean fuel injectors. Our services usually resolve these problems and returns the injectors to their optimal efficiency.


In the rare circumstance that an injector cannot be repaired, it is possible to isolate and replace it separately, saving you the high cost of replacing the entire set.

In-House Rebuild Services

Mating surface seals should always be replaced after removing an injector from the fuel rail or intake.


Grommets, spacers, and pintle caps may become brittle, loose, cracked, or worn out. During our in-house rebuild service, We replace all of those small parts as standard procedure so you don't have to waste time looking for them.


However, if you only require parts, we can assemble injector seal kits for nearly any application on-site.

  • Analysis of Current Condition of Injector

Repeat the Analysis of Current Condition of Injector

  • Flow rates scrutinized, and spray patterns analyzed
  • All passing injectors are reassembled with new filters, seals, pintle caps, and other components as needed.
