Perkins original Perkins 250-1306 Diesel Fuel Injector for 3508B 3512B 3516B PM3508B PM3516B Engine, Replacement for OEM original new injector

The Perkins 3512B diesel fuel injector, OEM reference 250-1306, is engineered as a direct-fit replacement component for Perkins 3512B, 3512C, 3516B, and 3508 series diesel platforms. Manufactured using high-precision CNC machining processes, each injector is built from hardened alloy steel to deliver exceptional wear resistance, corrosion resistance, high-temperature tolerance, and fatigue strength required for continuous-duty industrial operation. Calibration meets OEM fuel delivery standards, ensuring consistent spray patterns, optimized atomization, and stable injection pressure across varying load conditions.

This injector assembly is designed to enhance fuel economy through refined injection timing and improved thermal efficiency, reducing overall operating costs for generator sets, marine propulsion systems, mining machinery, oil and gas equipment, and construction applications. Heavy-duty industrial construction supports long service life in harsh environments, and complete cross-reference compatibility with 326-1643, 10R-7222, 317-7630, and related part numbers provides flexible replacement options for global fleet operators. A 12-month warranty backs every brand-new unit.

Installation requires verifying the part number, cleaning the injector bore, inspecting fuel lines, replacing sealing washers, and confirming cylinder head condition. Operators should use clean diesel fuel, install new sealing components, follow OEM torque specifications, and avoid contamination during fitting. Routine maintenance—including regular fuel filter replacement, water separator draining, and periodic injector bench testing—helps prevent hard starting, black smoke, white smoke, excessive fuel consumption, and rough idle, sustaining reliable engine performance in demanding industrial, marine, and power generation fields.
