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.
