Frequently Asked Questions About Freightliner FL70-FL80 Fuel Tank Brackets & Straps

What years and models of FL70 and FL80 trucks are these fuel tank brackets compatible with?

Our fuel tank brackets and straps are designed to fit Freightliner FL70 and FL80 models from 1994 through 2007. However, compatibility can vary based on your specific tank configuration (25-gallon, 50-gallon, or 100-gallon tanks) and whether you have single or dual tank setups. We recommend checking your existing bracket part numbers or contacting us with your VIN to ensure proper fitment, as some mid-year production changes may affect compatibility.

Are these brackets made from steel or aluminum, and will they rust over time?

Most of our FL70-FL80 fuel tank brackets are constructed from heavy-gauge steel with either a black powder coat or zinc-plated finish for corrosion resistance. The steel construction provides superior strength compared to aluminum alternatives, especially important for supporting heavy fuel loads. While the protective coatings significantly reduce rust risk, we recommend periodic inspection and touch-up of any chips or scratches, particularly if you operate in areas with road salt exposure.

Can I install these brackets myself, or do I need special tools?

Installation typically requires basic hand tools including socket wrenches, a torque wrench, and potentially a floor jack to support the tank during bracket replacement. Most experienced DIY mechanics can complete the installation in 2-3 hours per tank. The main challenges include safely supporting the fuel tank weight (especially when full) and accessing tight mounting points. We strongly recommend draining the tank before installation and having a helper assist with tank positioning.

How do I know if I need just the straps or the complete bracket assembly?

If your straps show signs of stretching, fraying, or corrosion but the mounting brackets remain solid and properly aligned, you may only need replacement straps. However, if you notice bent brackets, broken welds, cracked mounting points, or excessive rust on the bracket assembly itself, you'll need the complete bracket kit. Many customers choose to replace both components together since labor costs are similar and it ensures all mounting hardware is fresh.

What's the difference between OEM and aftermarket brackets for these trucks?

OEM brackets are manufactured to original Freightliner specifications and typically carry a higher price point. Our aftermarket options are built to meet or exceed OEM standards for fit and durability, often featuring improved coatings or reinforced stress points based on common failure areas. The main differences you'll notice are price (aftermarket is usually 30-40% less expensive) and occasionally minor variations in finish appearance. Both options will securely mount your fuel tank when properly installed.
