No hidden fees. No surprises on your invoice. Here's exactly how it works.
Pricing is per injector based on type. Two injector minimum per order. Every service includes a detailed diagnostic report with before and after flow rates, spray pattern assessment, and variance analysis.
| Service | Price | Details |
|---|---|---|
| Top Feed Injector | $25/ea | Full ultrasonic cleaning, flow testing, and calibration. Most common marine injector type. Includes o-rings and standard rebuild components. |
| Side Feed Injector | $30/ea | Yamaha HPDI, Mercury EFI, and similar side feed designs. Includes o-rings and standard rebuild components. |
| GDI Injector | $30/ea | Gasoline direct injection. Specialized high-pressure cleaning and flow testing. Includes o-rings and standard rebuild components. |
| Optimax Air Injector | $40/ea | Mercury Optimax series. Specialized cleaning and flow testing procedure. Includes standard rebuild components. |
| Flow Test Only | $15/ea | Spray pattern and flow rate testing without cleaning. If your injectors test within 4% variance, cleaning may not be necessary. We'll contact you with results before proceeding. |
Every cleaning service includes the full workup: visual inspection, ohm and resistance testing, leak down testing, spray pattern analysis, precision flow testing, ultrasonic cleaning with back-flush cycles, and new o-rings, seals, and filter baskets. Your injectors come back rebuilt with fresh components — not just cleaned.
If your injectors need specialty parts like pintle caps or non-standard seals, we'll contact you with the cost before installing anything. You'll never see a surprise charge on your invoice.
We specialize in marine gasoline fuel injectors for outboard engines from 40HP to 350HP. Our service covers top feed, side feed, GDI (gasoline direct injection), and Optimax air injector types across all five major outboard manufacturers: Mercury, Yamaha, Honda, Suzuki, and Tohatsu.
We do not currently service: diesel injectors or Evinrude E-TEC direct injection.
Two ways to get your injectors to us. Choose whichever works best for you.
Fill out our online shipping form and we'll email you a UPS QR code. Take it to any UPS location, they'll scan the code, print your label, and ship your package. No printer needed. Inbound shipping is charged on your service invoice after your injectors are cleaned and returned.
Download our PDF shipping form, fill it out by hand, and include it in the box with your injectors. Ship with any carrier you prefer — UPS, FedEx, USPS. You handle inbound shipping and costs directly with the carrier of your choice.
We ship your cleaned injectors back to you via UPS Ground. Return shipping is a line item on your service invoice. Tracking information is emailed to you when your package ships.
All shipments — inbound and return — include $1,000 declared value coverage through UPS by default. The cost is approximately $17 per direction and appears as part of your shipping line items on the invoice.
You can decline insurance during checkout. If you do, UPS standard carrier liability applies (typically limited to $100). Dialed Injectors is not responsible for packages that are lost, stolen, or damaged during transit when insurance has been declined. This applies to both inbound and return shipping.
If you need coverage above $1,000, contact us and we'll work with you on additional declared value.
We don't charge anything upfront. You receive a single invoice after your injectors are cleaned, tested, and ready to ship back. The invoice covers everything: service, parts, inbound shipping (if you used our paperless option), and return shipping.

Most orders are completed within 2 business days of receipt. That's from the day we open your package to the day your injectors ship back. Transit time depends on your location and the carrier used.
If we find anything during testing that requires your input, we'll contact you. Otherwise, we will keep you updated on progress via email.
We keep you in the loop without flooding your inbox. Here's when you'll hear from us:
Email: Order confirmation when we receive your injectors, invoice when service is complete, and tracking information when your package ships back.
Phone: We call you directly if there is anything unexpected that significantly affects your cost or timeline. Reach us at (864) 400-5775.
If your injectors come back and something doesn't seem right, call us. We'll look at the data together and figure out what's going on. If we missed something, we'll make it right.
But we'll also be straight with you. Some injectors are past the point of cleaning — internal wear, damaged coils, cracked bodies. No amount of ultrasonic cleaning fixes that. When that happens, we'll tell you which ones need replacing, label them clearly so you know exactly which injector is the problem, and help you source the right replacement.
We hold completed injectors for 30 days after invoicing. If we don't hear back within 30 days, we'll reach out one more time before closing the order out. If you need more time, just let us know. Don't ghost us. We're happy to work with you.
We collect your name, email, phone number, and shipping address to process your order and communicate about your service. That's it. We don't sell your information, we don't share it with third parties, and we don't add you to marketing lists without your permission. See our full Privacy Policy for details.
