Premium Fuel Injector Cleaning And Testing for Port Injectors
From Auto to Marine; we use the latest Zapp GS8 to accurately measure whether your port injectors are operating within the required tolerances.
Along with traditional high-temp pulsed ultrasonic cleaning, we utilize our proprietary state-of-the-art POWERFLUSH to further internally clean Port fuel injectors. Our competitive edge comes from this technology, along with our custom tooling and well-honed processes. Every part of our system and process are designed to clean injectors efficiently, reduce turnaround time, and deliver exceptional results. With unmatched precision and attention to detail, we’re the top choice for high-quality fuel injector servicing.
Injector parts are always replaced as part of our standard service. We do not offer a no-parts or testing-only option. Our service is provided exclusively as a single, premium-tier offering.
- If an injector is found to be permanently defective, we will not proceed with the service. Instead, we will issue a refund for the cost of the injector, minus a $5 bench fee.
- Our fuel injector cleaning service includes up to six cleaning steps, including a POWERFLUSH stage when needed for stubborn injectors. This approach can greatly enhance the outcomes compared to conventional ultrasonic cleaning methods alone.
- Our Port fuel Injector tests are all carried out on the latest Carbon Zapp machines.
- As part of our premium service, you will receive new fuel injector components, including filters, O-rings, seals, caps, grommets, clips, spacers, decouplers, clamps, ferrules, caps and hoses, with OEM options generally available for all injector types.
- We include a Color Injector result report with all our injector service options shown below.
- Please note that some parts for certain injectors may occasionally be on back order, and we will inform you if this occurs.
- We capture video and photo evidence of each step of your injector service and send them to you as the work progresses.

Our standard injector service includes an additional POWERFLUSH cleaning stage for Top Feed, Side feed, E-TEC, Optimax Air, GDI and Piezo Injectors.
Yes, we have a 2 injector minimum.
Absolutely! Rest assured that we will take care of removing the injectors for you for (typically GDI and side feed) and invoice you for a bench fee of $10 per rail to do the work as problems can often arise. However, it’s important to note that we cannot be held responsible for any potential damage that may occur during the removal process. To ensure a smooth experience, we recommend that you personally remove the injectors from the rail.
To avoid any issues with shipping service secure them in plastic and tape them to prevent leaks.
For your convenience, side feed injectors will be re-installed in the fuel rails, top feed and GDI injectors will be packaged separately. GDI Injector clips are very easy, you’ll have no issues, but they are tricky to get off which we will do if you wish.

When preparing the injectors for shipping, it is strongly advised to place them inside a regular zip lock bag first. This will help to keep the fuel smell contained. It is important to avoid any damage during transit, so make sure not to simply toss the bag into a box without any additional packing material. This is particularly crucial for the pintle end.
It is not recommended to ship the injectors in a bubble envelope. Optimal protection can be achieved by using a box with some padding or a bubble envelope in a box. The small flat rate box from the Post Office may be good budget-friendly option for smaller injectors.
We charge flat rate shipping per item type for most items where specified as ‘Free Shipping’. Other Shipping charges are listed in the store per based on quantity.
We recommend insuring the package you are sending for the exact value of the items you are shipping, so that you can easily replace them if needed in the event you need to file a claim. Adding additional insurance beyond the items value will accomplish nothing.
