Fuel Injector Service

Professional Fuel Injector Cleaning and Flow Testing Service

Total Performance Racing offers fuel injector cleaning and flow testing with our ASNU computer-controlled injector testing machines. We provide professional ultrasonic injector cleaning and can flow test up to 8 injectors at once for an accurate side by side comparison.

Complete Cleaning and Flow Testing of Gasoline injectors for
only $28 per injector.

Price includes parts and before/after test data.

Why Have Your Injectors Cleaned?

Off-the-car injector cleaning and testing is the only way to verify that each injector is doing its job and allowing each cylinder to operate evenly for peak performance that can also improve fuel economy.

Replacement cost of a new fuel injector can be $150 or more. With our cleaning service, we can restore most fuel injectors to like-new condition for a fraction of the cost of a new injector. Most injectors can be restored to a like-new condition through our ultrasonic cleaning process and then verified with our testing process.

On today's computer-controlled engines the oxygen sensor(s) can only average the air / fuel mixture of all the cylinders. This can cause some cylinders to run rich and others to run lean if all the injectors are not flowing equally. Side by side flow testing is the only way to verify they are working well together. We can also service cold-start injectors.

Our 11 Step process includes the following:

1. Injectors are externally cleaned, visual inspected, and numbered.
2. Test injectors for resistance, shorts, and current draw.
3. Perform leak test, spray pattern, resistance while operating, and flow testing, (both pulsed and static), on one of our flow benches. Our modified test machines are set up specifically for various types of injectors. The test results are recorded.
4. Remove filter baskets, o-rings, pintle caps, etc.
5. The injectors are placed in our ASNU ultrasonic cleaning tank to remove any particles, grease, etc from the exterior that may contaminate the next two cleaning processes.
6. Into the second temperature controlled ultrasonic tank they go, the injectors are now cycled on and off allowing the ultrasonic energy to dislodge any particles and build-up inside the injectors.
7. The injectors are now placed in our third ultrasonic tank for additional cleaning using a different cleaning solution. Once again, they are being cycled on and off while being cleaned. These three tanks, two cleaning solution cleaning process insures that any particles or contaminates are removed.
8. A high pressure back-flush is now done to remove any remaining particles inside.
9. Back to the flow bench for retesting of spray pattern, flow rate, coil resistance, and leak checking. If any injectors still are not flowing well, they will go back through the cleaning process and retested as many times as needed. This test data is also recorded.
10. Install new filter baskets, o-rings, seals, and pintle caps (where applicable)
11. Prepare a comprehensive test report with before and after test data. The injectors are then packed along with the old parts for return.
