10R-1273 Ca-terpillar C15/C15 ACERT Reman Fuel Injector (EUI) – Replaces 249-0709 239-4909

This electronic unit injector (EUI) is a direct, OEM-equivalent replacement for Cat-erpillar C15, C16, C18, C27 and C32 diesel engines. Cross-referenced against OEM part numbers 289-0753, 291-5911, 294-3500, 295-9085, 356-1367 and remanufactured numbers 20R-5036, 10R-7230, 10R-8988, 10R-8989, 10R-1273, it is a true bolt-on fit with no core required.

Each unit is flow-matched and 100% bench-tested for injection pressure, spray pattern and delivery volume — delivering consistent firing, faster cold starts, better fuel economy and lower smoke across the full load range. The hard-coated plunger resists wear from today's low-sulfur diesel, extending service life between overhauls.

Proven across the toughest applications: 631K/637K/657G-class scrapers, 772/772G haul trucks, 834K dozers, 988K wheel loaders, 390D L track excavators and SR4/SR5/SR4B generator sets. Always verify fitment by engine serial number (ESN) before ordering.
