Frequently Asked Questions About International DuraStar Diesel Fuel Tanks

What sizes and capacities are available for International DuraStar fuel tanks?

International DuraStar fuel tanks typically range from 50 to 150 gallons in capacity. The most common sizes are 50, 60, 80, 100, and 120-gallon options. Tank dimensions vary based on capacity, with 50-gallon tanks measuring approximately 19" x 24" x 28" and larger 100-gallon tanks around 23" x 34" x 35". Always verify your frame rail spacing and available mounting area before ordering, as DuraStar models from 2008-2018 may have different chassis configurations.

Which model years and specific DuraStar models are these tanks compatible with?

These diesel fuel tanks are designed for International DuraStar 4200, 4300, and 4400 models primarily from 2002 to 2018. The 4300 series (2008-2018) uses 25-inch strap spacing, while earlier models (2002-2007) typically use 23-inch spacing. DuraStar 4400 models may require different mounting brackets depending on whether you have a single or crew cab configuration. Always check your VIN-specific details or existing tank measurements for exact fitment.

What material options are available and how do they compare for durability?

DuraStar fuel tanks come in two primary materials: aluminum and steel. Aluminum tanks are lighter (reducing overall vehicle weight by 40-60 pounds), resist corrosion better, and typically last 15-20 years. Steel tanks are more affordable upfront but require regular inspection for rust, especially in salt-prone regions. Both options feature reinforced baffles to reduce fuel sloshing. For maximum longevity in harsh climates, we recommend aluminum with a polished or brushed finish.

What installation hardware is included and what additional parts might I need?

Most replacement tanks include mounting straps and basic hardware, but you'll typically need to purchase sending units, fuel pickup tubes, and vent lines separately. Step tanks require specific mounting brackets (usually sold separately for $75-150). You'll also need new rubber isolators, fuel line fittings, and potentially a new fuel cap if switching between vented and non-vented systems. Budget an additional $100-200 for complete installation hardware beyond the tank itself.

Can I install these myself or do I need professional installation?

While experienced mechanics can complete the installation in 2-4 hours, we recommend professional installation for safety reasons. The process requires draining existing fuel, disconnecting fuel lines and electrical connections, and properly torquing mounting hardware to 65-75 ft-lbs. Improper installation can lead to fuel leaks or tank shifting. If self-installing, you'll need a transmission jack or tank jack for safe handling, as empty 100-gallon tanks still weigh 85-100 pounds.
