International Fuel Tanks

Frequently Asked Questions About International Fuel Tanks

What International truck models and years are these fuel tanks compatible with?

Our fuel tanks are designed to fit International models including the ProStar (2008-2016), LoneStar (2009-2017), 9900i (2000-2016), 9400i (2000-2016), and 5900i SBA (2001-2011). Each product listing specifies exact model compatibility. For trucks with aftermarket modifications or custom chassis setups, we recommend calling our tech support at 1-888-875-7787 to verify fitment before ordering.

What's the difference between aluminum and steel fuel tanks, and which should I choose?

Aluminum tanks are lighter (reducing overall vehicle weight by 50-100 lbs), resist corrosion better, and typically last 15-20 years. Steel tanks cost about 30% less upfront, are more impact-resistant, and easier to repair if damaged. Most owner-operators prefer aluminum for weight savings and longevity, while fleet operators often choose steel for the lower initial cost. Both meet DOT requirements when properly maintained.

Do I need special brackets or hardware to install these tanks, or can I reuse my existing mounting equipment?

Most replacement tanks use your existing mounting straps and brackets if they're in good condition. However, we strongly recommend inspecting all hardware during installation. Replace any straps showing cracks, excessive rust, or stretching. New strap kits typically cost $45-85 and ensure proper tank security. Some aftermarket tanks may require different strap lengths - check the product specifications or contact us for guidance.

What tank sizes and shapes are available, and how do I determine the right capacity for my truck?

We stock round and D-shaped tanks from 50 to 150 gallons, with 100-120 gallon sizes being most common for long-haul applications. Measure your existing tank's diameter and length, plus the available frame rail space. D-shaped tanks maximize capacity in tight spaces, while round tanks are typically more affordable. Consider your typical routes - regional drivers often choose 80-100 gallon tanks, while OTR drivers prefer 120-150 gallons to reduce fuel stops.

How difficult is the installation process, and what tools or skills are required?

Installation typically takes 2-4 hours per tank for someone with basic mechanical skills. You'll need standard hand tools, a floor jack or tank jack, and ideally a helper for positioning. The main challenges are safely draining/removing the old tank (diesel weighs 7 lbs per gallon) and ensuring proper fuel line connections. Professional installation runs $150-300 per tank. Always disconnect the battery, drain fuel completely, and follow DOT regulations for fuel system work.
