Freightliner FL70-FL80 Fuel Tank Brackets & Straps

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

Will these brackets and straps fit my specific FL70 or FL80 model year?

Fuel tank mounting components can vary by model year, cab configuration, and tank diameter, so it is important to check the fitment details listed on each product page before ordering. If you are unsure, have your VIN or truck's build sheet on hand and reach out to our team so we can confirm the correct bracket or strap length for your specific setup.

What materials are these brackets and straps made from, and how well do they hold up to road conditions?

Most fuel tank brackets and straps are constructed from steel and often feature a protective coating, such as powder coat or zinc plating, to help resist rust and corrosion from road salt, moisture, and general wear. Choosing a coated or treated option can help extend the service life of the part, especially for trucks that run in harsher climates.

How do I know if I need a bracket, a strap, or both?

Brackets typically support the fuel tank from below or the side and attach to the frame rail, while straps wrap around the tank to hold it securely in place against the bracket. In many cases you will need both working together, so check whether your tank is missing the mounting bracket, the strap, or the fasteners before placing an order.

Are these parts straightforward to install, or should I have a professional handle it?

Installation generally involves supporting the fuel tank, removing the worn or damaged bracket and strap, and bolting on the replacement using the original mounting holes on the frame rail. While many experienced technicians and shop owners handle this job themselves, the fuel tank is heavy and needs to be properly supported during removal and installation, so this is a job best suited for someone comfortable working under a truck with the right lifting equipment.

How can I tell if my current bracket or strap needs to be replaced?

Common signs include visible rust or corrosion, cracks or bends in the metal, a fuel tank that shifts or sags, or unusual noise or vibration coming from the tank area while driving. If you notice any of these issues, it is a good idea to inspect the brackets and straps closely and replace them before they fail completely, since a compromised mount can lead to fuel tank damage or leaks.
