Frequently Asked Questions About Freightliner FL70-FL80 Fuel Tank Accessories

What years and models are these fuel tank accessories compatible with?

Our fuel tank accessories are designed specifically for Freightliner FL70 and FL80 models manufactured between 1992 and 2010. Most accessories fit both 50-gallon and 100-gallon tank configurations. However, mounting brackets and straps may vary between pre-2000 and post-2000 models due to frame rail changes. Always verify your specific year and tank size before ordering to ensure proper fitment.

Are the fuel tank straps and brackets made of stainless steel or regular steel?

We offer both stainless steel and powder-coated steel options for fuel tank straps and brackets. Stainless steel accessories provide superior corrosion resistance and typically last 5-7 years longer than standard steel in harsh conditions. Powder-coated steel options are more budget-friendly and work well in moderate climates. All mounting hardware is zinc-plated for additional rust protection regardless of the strap material you choose.

How difficult is it to install fuel tank steps and do they require drilling?

Fuel tank steps typically require 2-3 hours for installation and do require drilling 4-6 mounting holes into your fuel tank. The process involves marking hole locations using the provided template, drilling with a step bit, and securing with stainless steel bolts and rubber washers. Most customers with basic mechanical skills can complete the installation using standard hand tools. We recommend applying sealant around all mounting points to prevent moisture intrusion.

What finish options are available for fuel tank covers and do they affect fuel temperature?

Fuel tank covers come in polished aluminum, brushed aluminum, and chrome-plated steel finishes. Polished aluminum is the most popular choice, offering excellent heat reflection that can reduce fuel temperature by 5-10 degrees in direct sunlight. Chrome provides the highest shine but requires more maintenance. All covers include insulation backing that helps maintain consistent fuel temperature and reduces condensation inside the tank.

Will aftermarket fuel tank accessories void my warranty or affect DOT compliance?

Properly installed fuel tank accessories that don't modify the tank structure or fuel system components will not void manufacturer warranties. All our fuel tank steps, guards, and covers are DOT compliant when installed according to instructions. However, any modifications that compromise tank integrity, such as improper drilling or welding, could affect both warranty and compliance. Always follow installation guidelines and use approved mounting methods.
