Frequently Asked Questions About International 9900/i/ix Fuel Tank Covers & Bras

What material are these fuel tank covers made from, and how long will they last?

Most International 9900 series fuel tank covers are constructed from either 304 stainless steel or heavy-duty aluminum diamond plate. Stainless steel covers typically last 10-15 years with proper care, while aluminum options offer excellent corrosion resistance for 7-10 years. Both materials are designed to withstand road debris, weather exposure, and frequent washing. The mounting hardware is usually zinc-plated or stainless steel to prevent rust and ensure long-term durability.

Will these covers fit my specific International 9900 model year and fuel tank size?

Fuel tank covers for International 9900, 9900i, and 9900ix models are generally compatible across years 1994-2017, but tank diameter is critical. Most covers fit standard 25-inch diameter tanks (both 100 and 120-gallon capacities). However, some models came with 23-inch or 26-inch tanks, which require specific covers. Always measure your tank diameter at the widest point and check whether you have round or D-shaped tanks before ordering. Step tank configurations may require different covers than standard side-mount tanks.

How difficult is the installation, and what tools do I need?

Installation typically takes 30-45 minutes per tank and requires basic hand tools: a socket set, screwdrivers, and possibly a drill for certain mounting styles. Most covers use existing mounting points or strap-on systems that don't require drilling. The main challenges drivers report are accessing tight spaces behind the tanks and aligning multi-piece covers. Having a second person helps with positioning. Some covers come with template guides to ensure proper alignment before final tightening.

What styles and finishes are available for the 9900 series?

Common styles include full-wrap covers, half-moon designs, and tank bras that cover just the visible front portion. Finishes range from mirror-polished stainless steel, brushed stainless, powder-coated options in black or custom colors, and diamond plate aluminum in mill finish or polished. Some covers feature cutouts for fuel gauges, while others include LED light provisions. Plain, quilted, and louvered patterns are available to match your truck's aesthetic.

Do these covers affect fuel gauge visibility or tank access for maintenance?

Quality fuel tank covers are designed with gauge visibility in mind. Most feature precision cutouts or clear windows for fuel gauge access. For maintenance, look for covers with quick-release mounting systems or hinged designs that allow easy removal without tools. Some drivers prefer tank bras over full covers specifically because they leave the tank top accessible for inspections and repairs while still providing front protection and visual enhancement.
