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 20% higher than the GMC Terrain at $125. Supply also plays a role: Mercedes S Class has 4,953 priced listings versus 1,728 for GMC Terrain, 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 59% for the GMC Terrain, so buyers looking for top-condition units will find more options on the Mercedes S Class side.
The GMC Terrain average ($147) runs 18% above its median ($125), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
Our guide covers 11 model years for the GMC Terrain (2015–2025) but only 9 for the Mercedes S Class (2015–2023), so the GMC Terrain data reflects a broader range of generations.
The GMC Terrain fuel pump is interchangeable across 17 model years versus just 12 for the Mercedes S Class — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
At Grade B (good) condition, the Mercedes S Class is 25% cheaper ($113 vs $150) — 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.
