Frequently Asked Questions About International RH Fuel Tank Caps
Will these fuel tank caps fit my specific International truck model and year?
Our International RH fuel tank caps are designed to fit most International ProStar, LoneStar, and 9900i models from 2008 onwards. However, fitment can vary based on your specific tank configuration. We recommend checking your existing cap's thread size (typically 2" or 2.5") and comparing it with our product specifications. If you're unsure, contact us with your VIN and we'll help verify compatibility.
Are these caps vented or non-vented, and which type do I need?
We offer both vented and non-vented options. Vented caps are required for tanks without a separate breather system to prevent vacuum buildup. Non-vented caps are used when your tank has a dedicated vent line. Check your original cap or look for a separate vent tube on your tank. Using the wrong type can cause fuel delivery issues or tank damage.
What's the difference between locking and non-locking caps, and are the locks durable?
Locking caps feature a keyed cylinder to prevent fuel theft and tampering. Our locking mechanisms use stainless steel internals that resist corrosion from fuel vapors. Non-locking caps offer quicker access for frequent fueling. The locks typically last 5-7 years with regular use, and replacement lock cylinders are available separately if needed.
How difficult is installation, and do I need special tools?
Installation is straightforward and takes about 5 minutes per cap. Simply unscrew your old cap and thread the new one on hand-tight plus a quarter turn. No special tools are required, though some drivers use a strap wrench for extra grip. Make sure to clean the tank threads first and check the rubber gasket is properly seated to prevent leaks.
What materials are these caps made from, and how do they hold up to weather and fuel exposure?
Our fuel tank caps feature either heavy-duty aluminum or chrome-plated steel construction with fuel-resistant rubber gaskets. The aluminum caps resist corrosion naturally, while chrome options have a triple-layer plating process for durability. Both types withstand extreme temperatures, UV exposure, and constant fuel vapor contact. With proper maintenance, expect 8-10 years of service life.
