Our 3348701 dual gear fuel supply pump is a critical front-end fuel system component engineered exclusively for Cum-mins 15L ISX15, X15 and QSX15 electronic common rail engines. It delivers steady low-pressure fuel supply to the high-pressure injection pump, effectively eliminating weak acceleration, insufficient rail pressure, hard cold startup and power drop during full-load climbing caused by worn original feed pumps. Direct bolt-on installation without engine pipeline modification.
✅ Highway Trucks: Kenworth, Peterbilt, Freightliner, International heavy-duty semi trucks with X15 power
✅ Special Machinery: Mine haul trucks, oilfield fracturing power units, stationary X15 generator sets
Unique Core Product Competitive Advantages
Dual Intermeshed Gear Design For Constant Large Fuel Flow
Precision matched double gear structure maintains stable 5.5–6.5Bar output pressure under long-distance highway cruise and full-load uphill operation, eliminates fuel starvation during high-speed heavy haulage.
Hardened Alloy Gear Pair With Long Service Life
Internal driving and driven gears adopt carburized wear-resistant steel, effectively filter out tiny impurities in commercial highway diesel, reduce gear abrasion and avoid premature pump failure for long-haul fleets.
Full Flow & Pressure Bench Calibration Before Shipment
Every feed pump undergoes continuous flow stability test, pressure holding inspection and leakage detection on dedicated X15 fuel system test bench, consistent with Cum-mins OEM fuel supply curve.
Integrated OEM Standard Drive Gear & Sealing Assembly
Built-in same specification drive gear as original unit, perfect matching engine gear train; high-temperature resistant composite seals prevent fuel leakage under long-time high working temperature.
Two Quality Grades For Different Fleet Operation Needs
Brand-new feed pumps with all-new gear and seal components for high-mileage daily highway fleets; remanufactured pumps replace all worn internal parts and re-calibrated, ideal for cost-controlled regional truck maintenance.
