Frequently Asked Questions About International HX Fuel Tanks
What size fuel tanks are available for my International HX, and how do I determine the right capacity?
International HX fuel tanks typically range from 50 to 150 gallons per tank, with dual tank setups offering up to 300 gallons total capacity. To determine the right size, consider your typical haul distance, fuel economy (usually 5-7 MPG), and weight restrictions. Most long-haul drivers opt for 100-150 gallon tanks, while regional haulers often find 75-100 gallons sufficient. Check your door jamb sticker for factory tank specifications and ensure any upgrade stays within your truck's GVWR limits.
Will these fuel tanks fit my specific International HX model year, and what about mounting compatibility?
Our International HX fuel tanks are designed to fit 2017-2024 HX models, including HX515, HX520, and HX620 series. The mounting brackets and strap configurations vary between model years, particularly the change that occurred in 2020. Pre-2020 models use a 3-bolt strap system, while 2020+ models feature a 4-bolt design. Always verify your OEM and existing tank measurements before ordering. Tanks are typically 25" or 26" in diameter, with lengths varying based on capacity.
Are these aluminum or steel tanks, and which material is better for my application?
We offer both aluminum and steel fuel tanks for International HX trucks. Aluminum tanks are 40-50% lighter than steel equivalents, resist corrosion better, and are ideal for weight-conscious operations. Steel tanks cost about 30% less, offer superior impact resistance, and are easier to repair if damaged. For corrosive environments or maximum payload, choose aluminum. For heavy-duty vocational work where impact damage is likely, steel provides better durability.
What installation challenges should I expect, and can I install these myself?
Installation typically takes 2-4 hours per tank with basic tools including socket sets, jack stands, and fuel transfer equipment. Common challenges include aligning mounting brackets on older frames with corrosion, managing fuel line connections (especially on DEF-equipped models), and properly torquing strap bolts to 45-55 ft-lbs. You'll need to safely drain existing fuel, which requires proper containers and disposal methods. Many customers successfully DIY install, but shops typically charge $200-400 per tank for professional installation.
Do these tanks come with fuel gauges, vents, and other necessary components?
Most replacement tanks come as bare units without sending units, requiring transfer of your existing fuel level sensor, which uses a standard SAE 5-bolt pattern. Tanks include the filler neck connection but not the cap itself. Rollover vent valves are typically not included and should be purchased separately ($40-60 each) to meet DOT requirements. We recommend replacing fuel straps, mounting bushings, and fuel lines during installation for optimal performance and safety.
