original 250-1308 Diesel Fuel Injector for 3508B 3512B 3516B 3406 3508 Engine Excavator Construction Machinery Spare Parts Accessories original new injector

Engineered for the toughest industrial duty cycles, the 250-1308 diesel fuel injector delivers reliable high-pressure fuel atomization for 3512B, 3516B and 3508B heavy duty engines. Manufactured from hardened alloy steel, this direct replacement injector is precision-built to match OEM specifications and cross-references 2501308, 10R-1280, 1521887, 1628810, 2290195, 3861760, 3920208 and 0R7780, providing wide interchangeability across industrial diesel platforms.

This injector is optimized for demanding applications including generator sets, marine propulsion systems, mining trucks, drilling rigs, industrial power units and heavy construction machinery. Global operators across North American power generation plants, European offshore marine fleets, Asia Pacific shipyards, Middle East oilfield power systems and African mining infrastructure rely on this injector for stable output. Key benefits include improved fuel economy, lower emissions, enhanced power delivery, reduced smoke and extended engine life, backed by a 6–12 month warranty for operational confidence.

Installation is straightforward for trained technicians: disconnect the battery, relieve fuel pressure, remove the old injector, inspect and clean the bore, fit new OEM-grade sealing rings, torque to specification, reconnect fuel lines and prime the system through the bleed ports before performing a leak check. Routine fuel filter replacement and periodic injector performance testing extend service life and prevent unexpected failures, ensuring maximum uptime and lower total cost of ownership.
