Engineered for demanding heavy-duty operating environments, the 20R-5077 Fuel Injector GP-F delivers precision fuel delivery for C9.3, C9.3B, and C9.3 ACERT industrial diesel engines. Designed as a direct OEM-quality replacement, this common rail injector supports engine outputs across 250-340 HP, 250-375 HP, and 275-380 HP configurations, as well as C9.3 generator engines rated 250-350 kW and marine variants delivering 300-375 HP. Manufactured from hardened alloy steel with corrosion-resistant coating, the assembly is built to withstand operating pressures up to 2000 Bar.
The multi-hole precision nozzle ensures enhanced atomization efficiency, promoting optimized combustion performance, improved fuel economy, reduced smoke emissions, and stable idle operation. Precision-machined geometry maintains OEM dimensional accuracy, enabling faster engine response, higher thermal efficiency, and reduced maintenance costs across long service intervals. Typical applications include excavators (320, 323, 325), wheel loaders (950, 962, 966), motor graders (140, 150), CS Series compactors, DE Series generator sets, industrial power units, and commercial marine engines.
Recommended installation practice includes fitting new seals, verifying injector seat cleanliness, inspecting high-pressure fuel lines, performing ECM coding when required, and running a post-installation test. For sustained performance, use OEM-quality fuel filters, ultra-low sulfur diesel, and maintain clean fuel storage. Backed by a 12-month warranty, this injector is ideal for construction, mining, power generation, and marine fleet operations worldwide.
