Single Fuel Injector for Yanmar 3YM30AE / 3TNM72 / 3TNV74F / 3TNV80F Engine — 119C10-53000 / 71912553100

Yanmar's 3-cylinder diesel engines power everything from ocean-going sailboats to compact tractors and mini excavators. When a single injector fails, you'll notice it immediately on a 3-cylinder — rough idle, hard starts, excessive smoke, and loss of power. This precision-matched aftermarket injector is a direct-fit replacement for part numbers 119C10-53000 and 71912553100, engineered to restore OEM-spec fuel atomization and combustion performance. Brand new, ready to install, no modifications required.

Why Replace a Faulty Injector Promptly?

A single misfiring injector on a 3-cylinder engine forces the remaining two cylinders to compensate, increasing thermal stress and accelerating wear on the injection pump and other injectors. Replacing it at the first sign of trouble — rough idle, power loss, excessive smoke, or hard starts — is the most cost-effective way to protect your Yanmar engine and minimize downtime.
