Frequently Asked Questions About Freightliner Cascadia 113/125 Fuel Tank Covers-Bras

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

Our fuel tank covers are designed to fit Freightliner Cascadia 113 and 125 models from 2008 to present. However, there are slight variations between pre-2018 and 2018+ models due to the New Cascadia redesign. Pre-2018 models typically use covers with different mounting hole patterns than the newer versions. Always check the product description for specific year compatibility, or contact our team with your VIN number for exact fitment verification.

What's the difference between aluminum and stainless steel fuel tank covers?

Aluminum covers are lightweight (typically 8-12 lbs), cost-effective, and resist corrosion well but may show scratches more easily. They're ideal for drivers prioritizing weight savings and lower cost. Stainless steel covers are heavier (15-20 lbs) but offer superior durability, better resistance to road chemicals, and maintain their mirror finish longer with proper care. Both materials provide excellent protection, so your choice depends on budget and aesthetic preferences.

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

Installation typically takes 30-45 minutes per tank and requires basic hand tools: a socket set (usually 1/2" and 9/16"), drill with metal bits if new holes are needed, and a torque wrench. Most covers use existing mounting points on your fuel tank straps. The main challenge reported by customers is aligning the covers properly while working underneath the truck. Having a second person helps significantly. Some drivers recommend test-fitting before final installation to ensure proper clearance.

Do fuel tank covers affect fuel temperature or DEF system performance?

Quality fuel tank covers should not negatively impact fuel temperature or DEF systems when properly installed. Ensure at least 1/2 inch clearance between the cover and tank for proper airflow. Covers with ventilation slots or perforated designs provide additional airflow. Some customers in extreme climates report slightly cooler fuel temperatures with covers installed, which can actually improve fuel efficiency. Always maintain proper clearance around DEF tank heaters and sensors.

How do I maintain the finish on chrome or polished covers?

For chrome covers, use a quality chrome polish monthly and avoid abrasive cleaners. Wash with mild soap and water, then apply polish in circular motions. For polished aluminum or stainless steel, use metal-specific polishes and a microfiber cloth. Winter road salt requires more frequent cleaning - rinse covers weekly during salt season. Many drivers apply a coat of wax or sealant after polishing for longer-lasting protection. Avoid automatic truck washes with harsh brushes that can scratch the finish.
