The Infiniti Q50 average ($141) runs 31% above its median ($108), indicating a tail of high-priced listings — likely low-mileage or remanufactured units pulling the average up.
The Ram 3500 fuel tank is interchangeable across 20 model years versus just 13 for the Infiniti Q50 — that wider compatibility window means more donor vehicles in salvage yards and tends to push prices lower.
Buyer's checklist
What to check before buying a used fuel tank
- Verify fuel tank gallon capacity, wheelbase mounting straps, and exhaust heat shield clearance, especially across different cab/bed or trim options.
- Inspect plastic or metal tank shell for deep gouges, rust pinholes around seam welds, or swelling caused by over-pressurization.
- Confirm vapor emissions (EVAP) valve port configurations, filler neck diameter, and lock ring mounting style for the fuel pump module.
- Ensure the tank has been properly drained and flushed to avoid vapor safety hazards and contamination during transit.
