Perkins original  Fuel Injector 250-1304 2501304 for 3508B 3512 3516 3516B Diesel Engine Construction Machinery Aftermarket Replacement original new injector

The Perkins 250-1304 fuel injector is a genuine OEM replacement component engineered for the Perkins 3512B, 3512C, 3516B, 3516C, 3508B, and 3508C diesel engine platforms. Built as an electronic unit injector, it delivers precisely metered fuel through micron-level machining tolerances and multi-hole nozzle technology, ensuring superior atomization and consistent combustion across all 12-cylinder and 16-cylinder configurations. The injector body is manufactured from high-strength alloy steel with an anti-corrosion precision coating, providing extended service life against wear, high-temperature fatigue, fuel contamination, and corrosive operating environments found in marine engine rooms, mining sites, and continuous-duty power generation facilities.

This injector is a direct-fit replacement requiring no modifications, mounting to the cylinder head fuel injection port and torqueing to original Perkins specifications. It carries cross-reference compatibility with 10R-1278, 392-0225, 392-0226, 392-0212, 392-0213, and 392-0214, allowing fleet operators and service workshops to consolidate inventory across multiple Perkins engine series. The component meets ISO 9001 certification standards and is backed by a 12-month warranty, with global serviceability aligned to Perkins maintenance and overhaul procedures across North America, Europe, the Middle East, Africa, Southeast Asia, and South America.

Field-proven across diesel generator sets, standby and emergency power systems, tug boats, cargo ships, offshore support vessels, mining haul trucks, oil and gas drilling equipment, heavy construction machinery, and industrial pumping systems, the 250-1304 injector addresses common diesel engine symptoms including hard starting, black or white smoke, rough idle, power loss, high fuel consumption, and engine knock. Recommended maintenance intervals include 500-hour inspections of fuel filters, rail pressure, and return flow, plus 2000-hour injector balance testing, spray pattern inspection, and full fuel system cleaning to maintain peak engine performance throughout the operational lifecycle.
