Peterbilt 362 Fuel Tank Caps

Frequently Asked Questions About Peterbilt 362 Fuel Tank Caps

Will this fuel tank cap fit my Peterbilt 362 fuel tank?

Fuel tank caps are typically sized by thread diameter and neck style, so fit can vary depending on the tank manufacturer and the year of your truck. Before ordering, measure your existing cap or check the neck size on your fuel tank to make sure it matches the specifications listed on the product page. If you are unsure, our team can help confirm compatibility before you buy.

Are these fuel tank caps vented or non-vented?

Both vented and non-vented caps are used across different Peterbilt 362 fuel tank setups, and using the wrong type can cause fuel delivery or pressure issues. Check your current cap to see if it has a vent, or consult your truck's fuel system documentation, since swapping a vented cap for a non-vented one (or vice versa) is not recommended.

What materials are these caps made from, and how durable are they?

Replacement fuel tank caps are commonly available in chrome-plated steel, stainless steel, or durable plastic/composite construction. Metal caps tend to hold up better against corrosion and daily wear, while offering a finish that matches other chrome accessories on the truck. Choose based on the look and durability level you need for your application.

Does the fuel tank cap come with a lock, and how does it secure to the tank?

Some caps include a locking mechanism with keys to help deter fuel theft, while others are simple twist-on or lever-style caps without locks. Locking caps generally cost more but provide added security, especially for trucks parked in high-traffic or unsecured areas. Check the product listing to confirm whether a lock and keys are included.

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

In most cases, installation is straightforward: remove the old cap by unscrewing or unlatching it, then thread or secure the new cap onto the tank neck by hand. No special tools are typically required, but make sure the new cap seals tightly to prevent fuel leaks or vapor loss. If your cap includes a tether or chain, reattach it to the tank bracket before finishing installation.
