SE501958: John Deere Fuel Injector SE501958 | Delphi Reman EUI for 6125/6125H 12.5L Tier 2 – Replaces RE517658 RE517663

This Delphi electronic unit injector (EUI) is a high-quality aftermarket replacement for John Deere PowerTech™ 6125 (12.5L) and 6125H Tier 2 diesel engines (OH High Power variant). It replaces OE part number SE501958, cross-referenced to RE504092, RE508491, RE517658, RE517663, RG31719, RG33968, EX631013 and Delphi BEBE4B17103. Solenoid-actuated electronic control meters fuel precisely on every stroke for complete combustion — less smoke, lower emissions and better fuel economy. The high-strength steel body and hardened-alloy nozzle withstand sustained injection pressure and wear, with a copper base washer and O-rings for a tight, leak-free seal. Every unit is bench-tested for flow rate and injection pressure before shipment. Fits John Deere forage harvesters (7500, 7700) powered by 6125/6125H (12.5L) engines. Export-packed, 12-month warranty and responsive technical support. Aftermarket replacement part — not a genuine John Deere product.
