Perkins original 10R-1258 Common Rail Fuel Injector for C10 C11 C12 C13 Engine Construction Machinery Parts Replacement for OEM 212-3468 170-5242 original new injector

The Perkins 10R-1258 / 212-3468 Original Reman fuel injector is engineered for the Perkins C13, C12, C11, and C10 diesel engine family, serving heavy-duty truck, industrial, marine, and pumper equipment applications such as SBF214 and SUF557. Built around the Mechanical Electronic Unit Injector (MEUI) fuel system used on these inline six-cylinder, turbocharged and aftercooled platforms (12.0L and 12.5L displacement, 335–600 hp), this injector delivers OE-style fitment and precise fuel metering required for stable combustion, high-pressure atomization, and controlled fuel consumption under demanding load cycles.

As a Perkins Reman product, the unit is remanufactured to original equipment specifications, providing a reliable replacement option for fleet operators, engine rebuilders, and B2B distributors serving the global aftermarket. It helps restore engine performance, reduce vehicle downtime, and limit the risk of more expensive damage caused by worn, leaking, sticking, or electrically defective injectors. The injector is suitable for low sulfur fuel and is compatible with a wide range of part references, including 212-3468, 212-3463, 212-3465, 212-3461, 212-3466, 249-0708, 249-0709, and 10R-2977, simplifying cross-reference searching for wholesale and service applications.

For best service life, technicians should use clean diesel, replace fuel filters on schedule, drain the water separator, and inspect the injector harness and connectors. Fuel pressure should be checked when symptoms such as hard starting, rough idle, black or white smoke, misfire, low power, high fuel consumption, surging, or poor acceleration appear, and cylinder balance, leak, return flow, and ECM fault code tests should be performed before replacement. The related seal kit should be renewed whenever an injector is removed, and the fuel system should be bled and fault codes verified after installation to confirm proper operation.
