International S2100-S2300 Fuel Tank Caps

Frequently Asked Questions About International S2100-S2300 Fuel Tank Caps

Will this fuel tank cap fit my International S2100 or S2300 truck?

Fuel tank caps for the International S2100-S2300 series are designed to match the OEM fitment for these specific models, but fuel tank neck sizes and thread patterns can vary depending on the model year and tank manufacturer installed on your truck. Before ordering, check your existing cap for its diameter and locking mechanism style, or reference the part number if available, to confirm it matches the listing.

Is this a locking or non-locking fuel cap, and does it come with keys?

Product listings in this category typically specify whether the cap is a locking or non-locking style. Locking caps usually include a set of keys with the purchase, which helps deter fuel theft and tampering. If keys are not included or you need replacements, contact us before ordering so we can confirm what is provided with your specific cap.

What material and finish options are available?

Fuel tank caps are commonly available in chrome-plated steel, aluminum, or plastic construction depending on the specific part. Chrome and aluminum options tend to hold up better against corrosion and road exposure, while also matching the appearance of other chrome accessories on the truck. Check the individual product description for the exact material and finish before purchasing.

How do I install a replacement fuel tank cap?

Most replacement caps thread or clip directly onto the existing fuel tank neck the same way the original cap did, so installation generally does not require tools. Simply remove the old cap by turning or releasing it, then thread or seat the new cap into place until it is snug and sealed. If your cap includes a tether or vent feature, make sure it is oriented correctly so it does not interfere with fueling.

Does this cap include a vent to prevent pressure buildup?

Some fuel tank caps are vented to allow air to enter the tank as fuel is used, while others are non-vented and rely on a separate vent elsewhere in the fuel system. Using the wrong type for your truck can cause fuel delivery issues or tank pressure problems, so check whether your original cap was vented and choose a replacement that matches that function.
