Restoring Precision and Performance Across All Engine Types
At Fuel Injector Man, Inc., precision isn’t just a promise—it’s the foundation of everything we do. Located in Naples, Florida, we specialize in professional fuel injector cleaning and calibrated flow testing for a full range of gasoline engines, including marine, automotive, motorcycle, ATV, RV, and powersports applications.
From outboards to street cars, our process restores clean, balanced fueling that translates into smoother idle, stronger acceleration, improved fuel economy, and long-term engine reliability. Whether you operate a Yamaha HPDI, Mercury OptiMax, Evinrude E-TEC, or a high-performance automotive engine, properly serviced injectors ensure your engine performs exactly as intended.
We are known for honest communication, clear documentation, and meticulous workmanship. Every injector receives before-and-after flow testing, ultrasonic cleaning, new filters and O-rings, and a printed flow report for transparency.
We do not service diesel injectors—our focus remains strictly on gasoline-based precision systems where accuracy matters most.
Our Injector Cleaning & Flow Testing Process
Every injector we service undergoes a comprehensive, repeatable procedure designed to restore precision and reliability.
Visual and Electrical Inspection
We inspect each injector for leaks, cracks, corrosion, and electrical resistance.
Baseline Flow & Spray Testing
Injectors are tested “as-received” to record flow volume and spray pattern across duty cycles.
Ultrasonic Cleaning and Reverse Flushing
Specialized ultrasonic frequencies and solvents dissolve internal varnish, gum, and carbon, while reverse flushing removes trapped debris.
Filter and O-Ring Replacement
Each injector receives new internal filters and external O-rings to prevent leaks and ensure consistent operation.
Post-Clean Flow Verification
We re-test injectors under multiple pulse conditions to verify matched flow rates and uniform spray.
Results Report
Every customer receives a printed before-and-after report showing flow balance, percentage change, and variance.
Marine Fuel Injector Cleaning
Expert Service for Yamaha, Mercury, Honda, Suzuki, and Volvo Penta
Marine engines endure tough conditions—moisture, ethanol, and long idle or storage periods cause injectors to gum up or corrode internally. Our marine injector cleaning service is designed to handle both top-feed and side-feed designs, restoring the precision needed for smooth starts, consistent idle, and strong performance at every RPM.
We service:
- Yamaha 2-stroke, 4-stroke, and HPDI injectors
- Mercury Optimax air and fuel injectors
- Honda and Suzuki outboards
- Volvo Penta marine systems
- Evinrude 2-stroke and 4-stroke applications
What You’ll Notice:
- Faster, cleaner starts after storage
- Smoother idle and steady RPM at dock or cruise
- Stronger mid-range acceleration and quicker planing
- Better fuel economy and reduced smoke
- Longer engine life with balanced cylinder fueling
Pricing:
- Top-feed marine injectors: $20 per injector
- Side-feed/OptiMax injectors: $26 per injector
- Evinrude E-TEC injectors: $62 per injector (serviced as sets)
Turnaround: 1–3 business days depending on system complexity.
All marine injectors are returned with new filters and O-rings, balanced flow data, and documented spray verification.
Automotive Fuel Injector Cleaning
Port-Fuel Injector Cleaning for Cars and Light Trucks
Automotive injectors are precision components that deteriorate over time due to carbon buildup, poor fuel quality, and ethanol-blended fuels. When injectors become partially restricted, your engine compensates by enriching the air/fuel mixture, reducing efficiency and power.
Our automotive injector cleaning service eliminates these issues using the same process applied to marine injectors—ultrasonic cleaning, reverse flushing, and flow verification.
Common Symptoms We Fix:
- Rough or unstable idle
- Misfires or hesitation
- Poor fuel economy
- Loss of throttle response
- Hard starting after sitting
Ideal For:
- Passenger cars and light trucks (import and domestic)
- Performance/tuner vehicles using port injection
- Classic and restoration engines
- RVs, generators, and gasoline-powered auxiliary systems
Price: $20 per injector
Includes: Cleaning, filters/seals, flow testing, and report
Turnaround: 1–2 business days
We currently service port-fuel injection (PFI) systems only. Gasoline Direct Injection (GDI) and diesel injectors are not supported at this time.
Side-Feed Fuel Injector Cleaning
Specialized Service for Mercury OptiMax and Similar Designs
Side-feed injectors require more advanced service than typical top-feed designs due to their internal layout and fuel path configuration. Found commonly in Mercury OptiMax air and fuel systems and select automotive applications, side-feed injectors demand correct cleaning direction, seal seating, and fixture alignment for accurate results.
Our side-feed injector cleaning process includes custom fixturing for both marine and automotive side-feed units, ensuring contaminants are fully removed without damage.
What Makes This Service Unique:
- Reverse flushing under pressure to clear inlet contaminants
- Replacement of specialized internal filters
- Re-seating of O-rings and seals using correct OEM configurations
- Spray pattern verification under multiple pulse widths
Benefits:
- Restored balance between cylinders
- Reduced detonation risk from lean injectors
- Faster acceleration and smoother idle
- Lower fuel consumption and improved plug life
Price: $26 per injector
Turnaround: 2–3 business days
Each set is returned with a detailed flow report verifying consistent output across all injectors.
Evinrude E-TEC Fuel Injector Cleaning
Complete Set-Based Cleaning and Calibration Verification
The Evinrude E-TEC system uses electronically controlled injectors that are flow-calibrated from the factory. Unlike other systems, cleaning one injector in isolation can cause imbalance in the ECU mapping, so we service E-TEC injectors as complete sets only.
Our E-TEC process includes electrical resistance testing, ultrasonic cleaning, reverse flushing, and multi-point flow verification. Each set is balanced and returned with resistance and flow data for precise reinstallation.
Price: $62 per injector (set service only)
Includes: Ultrasonic cleaning, filter/seal renewal, electrical verification, flow documentation
Turnaround: 3–5 business days
E-TEC System Benefits:
- Smooth, even idle across all cylinders
- Restored top-end power and throttle response
- Reduced misfire or hesitation under load
- Improved combustion and lower fuel consumption
- Balanced set ready for ECU calibration
E-TEC injectors are among the most advanced marine components in use today, and our shop has the expertise and equipment to clean them safely and effectively.

Frequently Asked Questions
How often should injectors be cleaned?
Marine engines: every 200–300 hours or before each season.
Automotive engines: every 50,000–60,000 miles or as symptoms appear.
Can you fix injectors that fail electrically?
No. Cleaning restores flow but cannot repair electrical or mechanical failures. We’ll identify and document any faulty units.
Do you replace filters and seals?
Yes. Every cleaned injector receives new internal filters and O-rings for leak-free performance.
Can I ship my injectors to you?
Yes. Securely package injectors with your contact info and engine details. Ship directly to our Naples address; we’ll confirm receipt and turnaround.
Do you service diesel or GDI injectors?
No. We focus exclusively on gasoline marine, automotive, and powersports injectors.
