Market analysis
Why does the Mercedes S Class fuel pump cost more?
A used Mercedes S Class fuel pump carries a median asking price of $150, which is 40% higher than the Kia Seltos at $107. Supply also plays a role: Mercedes S Class has 4,953 priced listings versus 618 for Kia Seltos, and more listings generally mean more choices and more competitive pricing.
Grade A (excellent condition) parts make up 89% of Mercedes S Class listings compared to 67% for the Kia Seltos, so buyers looking for top-condition units will find more options on the Mercedes S Class side.
The Kia Seltos average ($133) runs 24% above its median ($107), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 9 model years for the Mercedes S Class (2015–2023) but only 5 for the Kia Seltos (2021–2025), so the Mercedes S Class data reflects a broader range of generations.

Buyer's checklist
What to check before buying a used fuel pump
- Match pump assembly module numbers, tank lock ring style, and quick-connect fuel line fitting diameters and counts (feed, return, and vapor lines).
- Check electrical connector pins for signs of heat scorching or melting, which indicates high current draw from an overheating motor.
- Inspect fuel level sender float arm and resistor wiper board for wear or corrosion that causes inaccurate gas gauge readings.
- Confirm whether the donor vehicle ran on standard gasoline, flex-fuel (E85), or diesel, as internal pump materials and flow rates vary accordingly.
