Market analysis
Why does the Mercedes E Class fuel pump cost more?

The Infiniti Q50 average ($132) runs 16% above its median ($114), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Only 67% of Infiniti Q50 fuel pump listings include a posted price (797 of 1,189 observed) — the rest are "call for price," which usually signals negotiable or higher-than-average pricing.
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.
