International 9300/9370 Fuel Tank Caps

Frequently Asked Questions About International 9300/9370 Fuel Tank Caps

Will this fuel tank cap fit my International 9300 or 9370?

Fuel tank caps for these models are generally designed to fit the factory fuel tank openings used on the International 9300 and 9370 series, but tank cap sizing can vary depending on the diameter of the fill neck and thread or locking mechanism used on your specific truck. Always check the listed measurements and thread type against your current cap or tank neck before ordering to make sure you get a proper fit.

Are these fuel tank caps vented or non-vented, and does it matter?

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 can cause fuel delivery issues or tank pressure problems, so it is important to match the venting style of the original cap that came on your truck.

Do these caps come with a locking feature to prevent fuel theft?

Many replacement fuel tank caps for the 9300 and 9370 are available in locking versions that use a key to help deter fuel siphoning, while others are simple non-locking caps. If theft prevention is a concern, look for a locking cap option and check whether a key is included with the purchase.

What material are these fuel tank caps made from, and how well do they hold up?

Fuel tank caps in this category are typically made from durable plastic or metal, often with a chrome or painted finish to match factory appearance. The material affects both durability and resistance to corrosion, so if you are running in harsh weather or high-mileage conditions, a metal or chrome-plated option may hold up better over time than a basic plastic cap.

How do I install a replacement fuel tank cap, and do I need any tools?

Most fuel tank caps are designed to thread on or snap into place without special tools, similar to removing and replacing the original cap. Simply remove the old cap by turning or unlatching it, then thread or seat the new cap in the same manner, making sure it seals tightly to prevent leaks, dirt intrusion, or fuel vapor loss.
