Genuine Bosch High Pressure Fuel Pump For Hyundai Tucson 2.0L 2.4L 35320-2G740

I. Product Positioning
A core original equipment-grade high-pressure fuel supply component specially designed for GDI/MPI direct injection/port fuel injection engines of Hyundai and Kia. It precisely matches OE specifications and provides an all-in-one solution to fuel system failures such as insufficient fuel supply pressure, weak acceleration, idle vibration, soaring fuel consumption, and difficult starting. It restores the engine’s original power and fuel efficiency with a high cost-performance ratio.

II. Core Functions
Ultra-high-pressure precise fuel supply: Stably outputs an operating pressure of 100–250 bar to meet the micron-level atomization requirements of direct injection engines, resulting in more uniform fuel mixing, a 15%–20% improvement in combustion efficiency, and complete elimination of “sluggish acceleration and weak power”.
Intelligent operating condition pressure regulation: ECU precisely controls fuel delivery volume and pressure, ensuring energy saving at idle and full fuel supply under high load. The response time is less than 1 ms, delivering smooth gear shifting and rapid acceleration without hesitation, with linear and stable power output.
Pressure retention and leak prevention upon engine shutdown: Built-in precision check valve maintains pipeline pressure after shutdown, enabling instant cold starts and eliminating fuel leakage and difficulties in restarting.
High-temperature and high-pressure durability: Withstands extreme engine compartment temperatures ranging from -40℃ to 150℃ and frequent high-pressure impacts, featuring reliable sealing and long-term stable performance without degradation.

III. Product Advantages
1. Original equipment-grade compatibility, zero obstacles to installation
Covers mainstream Korean models: Hyundai Elantra, Sonata, Tucson, Santa Fe, Kona; Kia K3, K5, Sportage, Sorento, Stinger and other GDI/MPI models.
Precisely corresponds to OE numbers: 35320-2G720, 35320-2G730, 35320-2B220, 35320-2E100, 35320-2GTA0, etc. Direct replacement without modification improves maintenance efficiency by over 50%.
Micron-level machining tolerance (0.01–0.03 mm) ensures tight fitting between the plunger and pump body, delivering stable installation and leak-proof sealing.

2. Premium materials, durable and rugged
Core plunger: Made of high-hardness alloy steel with nitriding/chrome plating hardening treatment, enhancing wear resistance by 10 times, resisting impurity abrasion, and avoiding scoring during long-term use.
Sealing system: Fluororubber/nitrile rubber offers oil resistance, high temperature resistance and anti-aging properties, eliminating fuel corrosion and leakage with a service life far exceeding ordinary parts.
Pump body: Cast from high-strength alloy, rust and corrosion resistant, compatible with E85 ethanol fuel and global fuel oil environments.
Built-in two-stage filtration (50μm at oil suction port, 10μm at oil outlet) effectively blocks impurities and protects the plunger and fuel injectors.

3. Cost-effective repair solution
Costs only 1/3 to 1/5 of replacing the original complete assembly, resolving core failures at a low cost with maximum cost performance.
One-time replacement completely repairs the fuel supply system, avoiding repeated maintenance and potential engine damage.
Quality comparable to original equipment, backed by a 1–2 year warranty for worry-free after-sales service.

IV. Applicable Scenarios (Fault Diagnosis)
Engine idle vibration, weak acceleration, slow power response, and a “stepping on cotton” feeling when pressing the accelerator.
Abnormally increased fuel consumption, with a rise of 2–5 liters per 100 kilometers and strong exhaust odor.
Difficult cold starts requiring multiple ignitions, occasional engine stalls during driving or illuminated malfunction indicator lamps.
Fuel system pressure test shows pressure below 80 bar, insufficient fuel supply and poor atomization.
