International ProStar Diesel Fuel Tanks

Frequently Asked Questions About International ProStar Diesel Fuel Tanks

Will an aftermarket diesel fuel tank fit my International ProStar without modification?

Most replacement and aftermarket fuel tanks in this category are designed to match the mounting configuration, capacity, and shape of factory tanks used on the International ProStar. However, tank fitment can vary by model year, cab configuration, and whether your truck has single or dual tank setups, so it's important to check the listed specifications and compare them to your existing tank's dimensions and mounting bracket layout before ordering.

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

Diesel fuel tanks for the ProStar are typically constructed from aluminum or polished aluminum, offering a good balance of corrosion resistance and weight savings compared to steel. Aluminum tanks also tend to hold up well against road debris and weather exposure, which is a common concern for drivers running long-haul routes in varying climates.

How do I know what tank capacity I need?

Fuel tank capacity depends on your original equipment setup and how your truck is configured, such as whether it uses single or dual tanks. Checking your current tank's capacity, usually stamped on the tank or listed in your truck's spec sheet, is the most reliable way to determine the right replacement size. If you're upgrading capacity, make sure the new tank's dimensions still clear your frame rails and other chassis components.

What's involved in installing a replacement fuel tank?

Installation generally involves draining and disconnecting the old tank, removing mounting straps or brackets, and transferring or replacing components like fuel lines, sending units, and vent fittings onto the new tank. Because this work involves fuel system components, it's important to follow proper safety precautions and torque specs, and many customers choose to have installation done by a qualified technician or shop familiar with heavy-duty trucks.

Do these tanks meet DOT and safety requirements for use on the road?

Fuel tanks sold for the International ProStar are built to work within standard heavy-duty truck fuel system requirements, but it's still the installer's responsibility to ensure mounting hardware, straps, and fuel line connections are properly secured and sealed after installation. If you have specific compliance questions for your fleet or jurisdiction, we recommend confirming details with your shop or safety officer before installation.
