Freightliner FLC120 Fuel Tank Brackets & Straps

Frequently Asked Questions About Freightliner FLC120 Fuel Tank Brackets & Straps

What do fuel tank brackets and straps actually do on my FLC120?

These components are responsible for securing the fuel tank to the truck's frame rail. Brackets typically mount to the frame and support the tank's weight, while straps wrap around the tank to hold it firmly in place and prevent shifting, vibration, or movement while driving. Together they keep the fuel tank stable and properly positioned under normal operating conditions.

How do I know if my brackets or straps need to be replaced?

Common signs include visible rust or corrosion, cracks or bends in the bracket metal, stripped or damaged mounting bolts, and a fuel tank that feels loose or shifts when the truck is in motion. If you hear rattling or notice the tank sitting at an angle, it's a good indication that the straps or brackets have worn out and should be inspected right away.

Will these brackets and straps fit my specific FLC120 fuel tank size?

Fit depends on your fuel tank's diameter and mounting configuration, since FLC120 trucks were built with different tank capacities over the years. Always check the listed measurements and specifications on each product page against your current tank and mounting setup before ordering to ensure proper fit.

What material and finish options are available for these parts?

Most fuel tank brackets and straps are made from steel or aluminum, often with a protective finish such as powder coating, galvanization, or plating to help resist rust and corrosion from road exposure. Choosing a corrosion-resistant option is generally recommended since these parts are mounted low on the frame and exposed to moisture, salt, and debris.

Can I install fuel tank brackets and straps myself, or do I need a mechanic?

Many owner-operators and shop technicians handle this replacement themselves, as the job typically involves supporting the tank, removing the worn bracket or strap hardware, and installing the new components using basic hand tools. However, since the fuel tank is heavy and needs to be properly supported during removal and installation, use a jack or additional help and follow proper safety precautions, or have a qualified technician perform the work if you're not comfortable doing it alone.
