Keep your Yamaha’s fuel rail sealed and vibration-free with the Rubber, Injector 68V-13766-00-00—the little cushion that does a big job on 150–225 hp HPDI and four-stroke V-6 powerheads. Pressed between the injector body and intake manifold, this OEM ring absorbs engine buzz, keeps salt spray out of the port, and maintains the airtight seal your ECU depends on to meter fuel perfectly.

Why the genuine grommet matters

• Fuel-resistant EPDM blend stays supple around ethanol blends and 180 °F under-cowl temps.

• Precision-molded 14 mm ID / 22 mm OD drops straight into the factory pocket—no trimming or RTV.

• Raised sealing lip distributes clamp load evenly so the injector sits square and won’t “walk” under throttle.

• Micro-ribbed exterior grips the bore, stopping the slow vacuum leaks that create lean sneezes at idle.

Swap it whenever you service injectors or track down a pesky air leak. The five-minute change rewards you with crisper starts, smoother trolling, and the peace of mind that every pulse of fuel is sealed tight inside the manifold—exactly the way Yamaha engineered it.
