Perkins original Perkins 386-1767 Fuel Injector Replacement for 3508B 3512B Construction Machinery  original new injector

The Perkins 3512B Fuel Injector 386-1767 is an original OEM injector GP engineered for the V12 Perkins 3512B diesel engine and compatible platforms including the 3512, 3512C, 3516B, 3516C, 3508, 3508B, 3508C, 3524, and 3524B. Built to stringent OEM manufacturing standards, this electronic unit injector serves as a precision fuel metering device, delivering atomized diesel fuel directly into the combustion chamber at precisely controlled timing intervals. Its multi-hole nozzle design significantly improves fuel atomization, combustion efficiency, fuel economy, emission performance, and overall engine responsiveness across demanding heavy industrial power applications.

Designed for harsh operating environments, the 386-1767 injector offers high temperature resistance, corrosion resistance, and an extended service life, ensuring stable power output for generator sets, marine engines, mining equipment, oilfield equipment, construction machinery, and continuous duty industrial power plants. The injector operates within a water-cooled electronic unit injection system, maintaining consistent injection pressure and balance rates that are critical for reliable engine performance in both land-based and marine generator set installations.

For proper installation, technicians should clean the cylinder head injector bore, install new sealing components, lubricate O-rings, mount the injector according to Perkins specifications, torque to factory values, bleed the fuel system, verify fuel pressure, and conduct operational testing. Routine maintenance includes the use of OEM fuel filters, clean diesel fuel, periodic injector bench testing, and monitoring of fuel pressure and injector balance rates. Replacement cross reference numbers 379-0509, 10R-3255, 386-1758, 392-0208, 386-1760, 20R-1272, 392-2000, 124-6351, 162-8811, 0R-8893, 0R-8691, 10R-1291, 20R-1276, 2290196, 2501315, and 3920215 are supported for flexible sourcing and fleet interchangeability.
