Restore your Yamaha outboard to peak power and performance with expert injector, pump, and fuel system refurbishment.

At InjectorRx, we specialize in restoring Yamaha High-Pressure Direct Injection (HPDI) systems to like-new performance. Whether your injectors, fuel pumps, or regulators need cleaning, testing, or complete refurbishment, our technicians use precision tools and OEM-quality parts to bring your system back to factory specs.

What Is Yamaha HPDI?

Yamaha’s High-Pressure Direct Injection (HPDI) technology delivers exceptional power, fuel efficiency, and lower emissions by injecting fuel at extremely high pressures. But even high-performance systems experience wear over time.
Deposits, fuel contaminants, and pressure loss can lead to issues like:

  • Reduced engine power

  • Hard starting

  • Increased fuel consumption

  • Rough idle or misfires

Regular cleaning and refurbishment keep your HPDI system running at its best — and extend the life of your engine.
