How to Choose the Right Replacement Gas Tank for Your Vehicle

Replacing your gas tank? Choosing the correct replacement is crucial to ensure proper fit, performance, and long-term reliability. Whether you’re restoring a classic truck or replacing a leaking tank, this guide will help you select the right fuel tank for your needs.
1. Match Your Vehicle Exactly
Start by confirming the year, make, model, and submodel of your vehicle. Many tanks look similar but vary in size, mounting style, or filler neck position. Even within the same vehicle line, options differ by bed size, cab style, or drivetrain configuration.
2. Know Where the Tank Mounts
Common mounting locations include:
- Side-mounted tanks: Popular in Ford, Chevy, and GMC trucks
- Rear-mounted tanks: Often found in most cars and compact pickups
- Cab or bed-mounted tanks: Seen in older or specialty applications
3. Choose Steel or Polyethylene
Steel tanks are heavy-duty and typically OEM-style but may corrode over time. Polyethylene (plastic) tanks are lightweight, rustproof, and often easier to install.
4. Direct-Fit Is Best
A direct-fit replacement is engineered to match your factory tank with no modifications. All tanks at Gas Tank Depot are selected to be drop-in compatible with the proper brackets, straps, and dimensions.
5. Consider What’s Included
Some tanks come with sending units, gaskets, or hardware. Always read the product description to know what’s included and whether additional parts are required.
