Adding your products to cart

The International 8600 TranStar Diesel Fuel Tank product lineup has you covered for heavy-duty hauling. Choose from tough aluminum fuel tanks ranging from 50 to 120 gallons. Each tank handles the long miles and still looks sharp. Installation is simple, with handy features like rear-fill ports and easy-install kits. Replacing an old tank or expanding fuel capacity? We've got everything you need. Keep your fuel secure with heavy-duty fuel tank bracket-straps to perfectly mount your fuel storage and hold everything firmly in place. While you're at it, don't forget to add a non-vented sturdy fuel tank cap to ensure safety and prevent leaks. Whenever you need to access your existing tank and install a replacement component, there's no doubt that you'll probably need some ergonomic fuel tank steps for easier access during fueling or maintenance. Looking to upgrade your mounting setup? Check out some International 8600 frame and chassis parts designed specifically for your tank and accessories. And while you're at it, consider upgrading related exhaust parts to keep your truck running smooth and efficient. These aftermarket add-ons are well worth the investment as an owner-operator. If you're looking to increase fuel capacity, reduce your weight with an aluminum tank instead of a stainless steel tank to get more fuel efficiency, or get an OEM-standard aftermarket alternative to a worn-out diesel fuel tank, our extensive selection of products is sure to have something for you. Get reliable performance mile after mile with the right diesel fuel tank and accessories for your International 8600 TranStar.

Frequently Asked Questions About International 8600 TranStar Diesel Fuel Tanks

Will this fuel tank fit my International 8600 or TranStar without modification?

Fuel tanks in this category are designed to match the mounting profile and dimensions used on International 8600 and TranStar models, but tank capacity, strap spacing, and fitting placement can vary by model year and original equipment configuration. Always check the listed dimensions, capacity, and mounting specs against your truck's original tank before ordering to confirm a proper fit.

What materials are these fuel tanks made from, and how does that affect durability?

Diesel fuel tanks for these trucks are typically available in aluminum or steel construction. Aluminum tanks are lighter and naturally resistant to rust, which can help with fuel efficiency and long-term corrosion resistance, while steel tanks tend to be heavier but offer added durability against impact. The right choice depends on your priorities around weight savings versus ruggedness.

What tank capacities and shapes are available?

These tanks come in a range of capacities and shapes, including standard round and rectangular styles, to match different chassis setups and fuel range needs. Be sure to compare the capacity and shape of the replacement tank to your current setup, especially if your truck has specific frame rail clearance or dual-tank configurations.

What is included with the tank, and will I need to transfer additional parts?

Most replacement tanks ship as the bare tank only, so straps, sending units, fuel lines, caps, and mounting brackets from your original tank will typically need to be transferred over or purchased separately. Check the product listing carefully to see what is included so you can plan for any additional parts needed for a complete installation.

Do these tanks meet DOT requirements for on-road use?

Fuel tanks intended for on-highway trucks like the International 8600 and TranStar are built to meet applicable DOT specifications for fuel system components. If compliance documentation is important for your fleet or inspection requirements, review the product details or reach out to our team to confirm certification information before purchasing.
