Market analysis
Why does the Mercedes E Class fuel pump cost more?
A used Mercedes E Class fuel pump carries a median asking price of $125, which is 33% higher than the Cadillac CT5 at $94. Supply also plays a role: Mercedes E Class has 5,164 priced listings versus 594 for Cadillac CT5, and more listings generally mean more choices and more competitive pricing.
The Cadillac CT5 average ($113) runs 20% above its median ($94), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 10 model years for the Mercedes E Class (2015–2024) but only 6 for the Cadillac CT5 (2020–2025), so the Mercedes E Class data reflects a broader range of generations.
The Mercedes E Class fuel pump is interchangeable across 15 model years versus just 11 for the Cadillac CT5 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade A (excellent) condition, the Cadillac CT5 is 20% cheaper ($100 vs $125) — the gap narrows compared to the overall median difference.
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.
