International 4700-4900 Fuel Tanks

Frequently Asked Questions About International 4700-4900 Fuel Tanks

What are the different fuel tank capacities available for International 4700-4900 trucks?

International 4700-4900 trucks typically accommodate fuel tanks ranging from 50 to 150 gallons. The most common sizes are 50, 60, 80, 100, and 120-gallon tanks. Your specific model year and chassis configuration will determine which sizes fit properly. Side-mounted tanks are available in both round and D-shaped styles, with D-tanks offering better ground clearance. Always verify your frame rail spacing and existing mounting bracket locations before ordering.

Will these fuel tanks fit my specific year International 4700 or 4900?

Most aftermarket fuel tanks are designed to fit International 4700 and 4900 models from 1989 through 2002. However, there are important differences between DT466 and T444E engine configurations that affect tank placement and strap lengths. Models from 1999-2002 may have different frame rail spacing than earlier years. We recommend checking your OEM and measuring your existing tank dimensions, mounting strap spacing, and frame clearance to ensure proper fitment.

What material options are available and which is best for my application?

Fuel tanks for International 4700-4900 trucks come in three main materials: steel, aluminum, and aluminized steel. Steel tanks are the most economical but require regular maintenance to prevent rust. Aluminum tanks are lightweight and corrosion-resistant but cost more and can be prone to stress cracks if not properly mounted. Aluminized steel offers a middle ground with good corrosion resistance at a moderate price point. For trucks operating in northern climates with road salt exposure, aluminum or aluminized steel is highly recommended.

Can I install a replacement fuel tank myself or do I need professional installation?

While fuel tank replacement is possible for experienced DIY mechanics, it requires proper safety equipment and procedures. You'll need tank straps, mounting brackets, fuel line fittings, and potentially a sending unit. The tank must be completely drained and properly vented during removal. Installation typically takes 3-4 hours and requires supporting the tank while aligning mounting straps. Many customers report difficulties with rusted mounting hardware on older trucks. Professional installation is recommended if you're uncomfortable working with fuel systems or lack proper lifting equipment.

Do these replacement tanks come with sending units, straps, and mounting hardware?

Most replacement fuel tanks are sold as tank-only units without sending units, straps, or mounting hardware. You'll typically need to transfer your existing sending unit or purchase a new one separately. Tank straps and mounting brackets are usually sold separately as well, though some suppliers offer complete kit options. When ordering, verify what's included and budget for additional components. Sending units for 1989-1998 models often differ from 1999-2002 units due to changes in the fuel gauge system.
