Frequently Asked Questions About International 9300/9370 Diesel Fuel Tanks

What sizes and shapes are available for International 9300/9370 fuel tanks?

Diesel fuel tanks for the International 9300/9370 are typically available in a range of capacities and shapes, including round and D-shaped (half-round) styles. Common capacities run from around 50 to over 150 gallons, so it's important to check the tank's diameter, length, and mounting configuration against your truck's frame and existing brackets before purchasing.

Will an aftermarket fuel tank fit my truck without modification?

Most replacement tanks are designed to match OEM dimensions and strap or bracket positions for the 9300/9370 series, but frame spacing, exhaust routing, and battery box placement can vary by model year and configuration. We recommend confirming your VIN-specific specs and measuring your current tank before ordering to avoid fitment issues.

What materials are these fuel tanks made from, and how do they hold up?

Fuel tanks in this category are commonly made from aluminum or steel. Aluminum tanks resist corrosion well and are lighter in weight, which can help with fuel efficiency, while steel tanks tend to be more affordable and durable against impacts. Your choice often comes down to budget, weight considerations, and personal preference for long-term maintenance.

How difficult is it to install a replacement diesel fuel tank?

Installation generally involves draining and disconnecting the old tank, removing mounting straps or brackets, and transferring or replacing fittings such as the fuel pickup, sending unit, and vent lines. While experienced technicians or shops can typically complete this in a matter of hours, it does require proper support equipment and care when handling fuel lines and electrical connections.

Are these fuel tanks compliant with DOT and safety regulations?

Reputable fuel tanks for the 9300/9370 are manufactured to meet DOT and FMVSS requirements for fuel system components. Even so, it's a good idea to verify that any tank you purchase includes proper certification documentation and that your installation follows recommended mounting and venting practices to remain compliant.
