RE505207: John Deere Fuel Injector RE505207 | Delphi EUI for 6105 10.5L / 6125 12.5L PowerTech – Replaces RE517659 SE501957

This Delphi electronic unit injector (EUI) is a high-quality aftermarket replacement for John Deere PowerTech™ 6105 (10.5L), 6125 (12.5L), 6125H and 6081 diesel engines. It replaces OE part number RE505207, cross-referenced to RG31717, RG33967, SE501957, RE508490, RE517659 and RE517662. 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 9000-series 4WD tractors (9120 to 9620) powered by 6105, 6125 or 6081 engines. Export-packed, 12-month warranty and responsive technical support. Aftermarket replacement part — not a genuine John Deere product.
