Frequently Asked Questions About Freightliner Columbia 112/120 Fuel Tank Covers-Bras

Will these fuel tank covers fit my specific Columbia model year?

Our fuel tank covers are designed to fit Freightliner Columbia 112 and 120 models from 2000-2017. However, fitment can vary based on your specific tank configuration. Columbia models typically come with either 60-gallon, 80-gallon, or 100-gallon tanks, and you'll need to match the cover size accordingly. For 2011 and newer models with the updated tank mounting brackets, some minor adjustments during installation may be required. We recommend measuring your tank diameter (typically 23" or 25") before ordering to ensure proper fit.

What's the difference between stainless steel and aluminum covers, and which holds up better?

Stainless steel covers offer superior corrosion resistance and maintain their shine with minimal maintenance, making them ideal for harsh weather conditions and road salt exposure. They're heavier (approximately 15-20 lbs per cover) but provide excellent long-term durability. Aluminum covers are lighter (8-12 lbs) and more budget-friendly, but require regular polishing to maintain their appearance and may show oxidation over time. Both materials are durable, but stainless steel typically lasts 10+ years with proper care, while aluminum may need replacement after 5-7 years of heavy use.

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 (usually 13mm and 15mm), Phillips screwdriver, and possibly a drill with metal bits if your tanks don't have pre-existing mounting points. Most covers use adjustable straps that wrap around the tank, though some models use bracket-mount systems. The main challenge is accessing the back side of the tank for strap routing. Having a second person helps significantly. No cutting or welding is required, and detailed instructions are included with each cover.

Do these covers actually protect against fuel theft, or are they just cosmetic?

While fuel tank covers do provide a visual deterrent and make quick access more difficult, they're primarily designed for appearance enhancement and protection from road debris. Most covers don't lock and can be removed with basic tools. For serious anti-theft protection, you'll need to pair them with locking fuel caps or aftermarket anti-siphon devices. The covers do excel at preventing rock chips, road salt damage, and UV fading on your tanks, which helps maintain resale value.

Which style works best with fairings and side skirts?

For trucks with full fairings, the tapered or aerodynamic-style covers work best as they follow the body lines and don't interfere with fairing attachment points. Half-moon or full-wrap styles may require fairing modifications on some setups. If you have chassis-mounted side skirts, ensure you choose covers with rear-mount straps rather than center-mount to avoid interference. Measure the clearance between your tank and fairing (minimum 2 inches recommended) before ordering. Plain polished styles offer the most universal fit, while styles with steps or grab handles may require additional clearance.
