International S2100-S2300 Fuel Tanks

Frequently Asked Questions About International S2100-S2300 Fuel Tanks

What specific International S-series models and years are these fuel tanks compatible with?

These fuel tanks are designed specifically for International S2100, S2200, and S2300 series trucks manufactured between 1989 and 2001. They fit both single and tandem axle configurations. However, compatibility can vary based on your truck's wheelbase and original tank configuration. We recommend checking your OEM or calling our technical support team at 1-888-875-7787 with your truck's specific details to ensure proper fitment before ordering.

What materials are these fuel tanks made from, and how do they compare to OEM tanks?

Our International S-series fuel tanks are constructed from aluminum. Aluminum tanks offer excellent corrosion resistance and are approximately 40% lighter than steel alternatives. Our aluminized steel tanks feature a protective aluminum coating that provides superior rust prevention compared to standard steel. Both options meet or exceed OEM specifications for durability and are DOT certified for highway use.

What fuel tank capacities are available, and can I upgrade from my original tank size?

We stock fuel tanks ranging from 50 gallons to 150 gallons for the S2100-S2300 series. The most common sizes are 75, 100, and 120 gallons. You can typically upgrade to a larger capacity tank, but this depends on your truck's frame rail spacing and available mounting area. Upgrading may require different mounting straps or brackets. Our product listings indicate which mounting hardware is included, and we offer complete mounting kits separately if needed for size upgrades.

How difficult is the installation process, and what tools or additional parts are required?

Installation typically takes 2-4 hours for experienced mechanics and requires basic hand tools including wrenches, sockets, and a floor jack or transmission jack to support the tank during installation. You'll need new fuel tank straps if yours are corroded or damaged. Most installations also require new rubber isolators, fuel line connections, and potentially a sending unit gasket. We recommend replacing the fuel filter and inspecting all fuel lines during installation. Professional installation is advised if you're not comfortable working with fuel systems.

Do these tanks come with sending units, and are they compatible with my truck's fuel gauge?

Most of our International S-series fuel tanks come as tank-only units without sending units installed. Your existing sending unit can typically be transferred to the new tank if it's in good working condition. If your gauge isn't reading correctly after installation, it's usually due to a grounding issue or incompatible sending unit rather than the tank itself.
