International 9300/9370 Fuel Tanks

Frequently Asked Questions About International 9300/9370 Fuel Tanks

What size fuel tanks fit the International 9300 and 9370, and how do I determine the right capacity for my truck?

International 9300 and 9370 trucks typically accommodate fuel tanks ranging from 50 to 150 gallons, with 100-gallon and 120-gallon tanks being the most common sizes. To determine the right capacity, check your door jamb sticker for the original tank specifications, or measure your existing tank's dimensions (length x diameter). Keep in mind that dual tank setups are popular on these models, allowing for 200-240 gallons total capacity. The mounting strap spacing on these trucks is standardized at 26 inches for most applications.

Are these fuel tanks compatible with both the 9300 and 9370 models, and what years do they cover?

Most aftermarket fuel tanks are designed to fit both International 9300 and 9370 models from 1987 through 2003, as these trucks share the same frame rail configurations and mounting points. However, there are some variations between early models (1987-1994) and later models (1995-2003) regarding fuel sending unit connections and vent tube routing. Always verify your specific year and whether you have a set-forward or set-back front axle configuration, as this affects tank placement and strap positioning.

What material options are available, and which is best for preventing corrosion and maximizing lifespan?

Fuel tanks for these trucks come in two primary materials: aluminum and steel. Aluminum tanks are significantly more popular due to their corrosion resistance and 50% weight savings compared to steel. They typically feature 0.125-inch thick walls and last 15-20 years in normal conditions. Steel tanks are less expensive upfront but require regular maintenance and coating to prevent rust, especially in areas using road salt. Most drivers report aluminum tanks paying for themselves within 3-5 years through weight savings and reduced maintenance.

What additional parts do I need for installation, and can I reuse my existing hardware?

A complete fuel tank installation typically requires new mounting straps, rubber isolators, and fuel line fittings. While some original hardware can be reused, we recommend replacing the rubber strap isolators (which deteriorate over time) and checking your fuel sending unit compatibility. You'll need a 5-wire sending unit for most 1995+ models and a 2-wire unit for earlier trucks. Don't forget to order new vent tubes, fuel pickup tubes, and anti-siphon devices if your state requires them. Most installations take 2-3 hours per tank with basic hand tools.

How do I choose between cylindrical and D-shaped tanks, and what finishes are available?

Cylindrical tanks are the standard choice for International 9300/9370 trucks, offering maximum capacity and easier mounting. D-shaped tanks are typically used only when extra ground clearance is needed or for specific side-mount applications. For finishes, polished aluminum is the most popular choice, though mill finish aluminum saves money and can be polished later. Some drivers prefer powder-coated black tanks for a stealthy appearance, though these may show scratches more easily. Consider your climate and maintenance preferences when choosing - polished tanks require regular cleaning to maintain their appearance but offer the classic truck look most drivers want.
