International LoneStar Fuel Tanks

Frequently Asked Questions About International LoneStar Fuel Tanks

What size fuel tanks are available for my International LoneStar, and how do I know which one fits my truck?

International LoneStar fuel tanks typically come in 80, 100, 120, and 150-gallon capacities. The correct size depends on your truck's year (2008-2019) and wheelbase configuration. Measure from the back of your cab to the center of your rear axle - trucks with 228" or shorter wheelbases usually fit up to 120-gallon tanks, while longer wheelbases can accommodate 150-gallon tanks. Always verify your truck's specific mounting bracket spacing before ordering, as International made minor changes throughout production years.

Are these fuel tanks made of aluminum or steel, and which material is better for long-term use?

Most replacement fuel tanks for the International LoneStar are made from either 14-gauge aluminized steel or polished aluminum. Aluminum tanks are lighter (saving 40-60 pounds), resist corrosion better, and maintain their appearance longer, but cost 20-30% more. Aluminized steel tanks offer excellent durability at a lower price point and handle impact better, though they may show surface rust after 5-7 years. Both materials meet DOT requirements and work with standard diesel fuel.

What tools and skills do I need to install a replacement fuel tank myself?

Installing a fuel tank requires intermediate mechanical skills and specific tools including a floor jack or transmission jack, socket set with extensions, fuel line disconnect tools, and proper safety equipment. The process typically takes 3-4 hours and involves draining the old tank, disconnecting fuel lines and sending unit wiring, removing mounting straps, and reversing the process with the new tank. Many customers report needing to transfer the fuel sending unit from their old tank. Professional installation typically costs $300-500 if you prefer not to do it yourself.

Will aftermarket fuel tanks work with my truck's original fuel gauge and DEF system?

Quality aftermarket fuel tanks are designed to work with your LoneStar's factory fuel sending unit and gauge system. You'll need to transfer your original sending unit to the new tank - the mounting holes are standardized across most manufacturers. For 2011 and newer models with DEF systems, ensure the tank you select has the proper auxiliary ports if your DEF tank is frame-mounted near the fuel tank. Some aftermarket tanks may require minor wiring extensions for the sending unit on certain model years.

Do these fuel tanks come with mounting straps, and are they direct bolt-on replacements?

Most fuel tanks are sold without mounting straps, as your existing straps typically transfer over if they're in good condition. These tanks are designed as direct replacements using your truck's existing mounting points - no drilling or frame modifications required. However, rubber isolation pads between the tank and straps should be replaced during installation (usually $15-25 for a set). Some vendors offer complete kits with new straps and hardware for an additional $75-150, which is recommended if your original straps show any corrosion or wear.
