Mack CV/GU Truck Fuel Tank Brackets & Straps

Frequently Asked Questions About Mack CV/GU Truck Fuel Tank Brackets & Straps

Will these fuel tank brackets and straps fit my Mack CV or GU model?

Fitment on Mack CV and GU series trucks can vary depending on tank size, mounting configuration, and model year. Before ordering, check the part number against your truck's existing bracket or strap, or confirm measurements such as tank diameter and mounting hole spacing. If you are unsure, our team can help verify compatibility using your VIN or the part number currently installed on your truck.

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

Fuel tank brackets and straps for Mack CV/GU trucks are typically made from steel, often with a protective coating or finish to resist corrosion from road salt, moisture, and general wear. The gauge and finish can vary by manufacturer, so if long-term durability in harsh climates is a priority, look at the product description for details on coating type before purchasing.

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

Brackets typically mount to the frame and support the tank from below or the side, while straps wrap around the tank to hold it securely in place against the bracket or frame rail. If your tank is sagging, shifting, or making noise while driving, inspect both components since a worn strap can put extra stress on the bracket, and vice versa. Replacing both at the same time is often recommended if either shows significant wear or rust.

Are these brackets and straps a direct bolt-on replacement, or will I need to modify anything?

Most replacement brackets and straps are designed to bolt into the original mounting points on the frame and tank, matching OEM hole patterns and dimensions. However, aftermarket variations can differ slightly in thickness or hole placement, so it is a good idea to compare the new part side by side with the old one before installation to confirm alignment and avoid drilling or modifying your frame.

How often should fuel tank brackets and straps be inspected or replaced?

Because these components are exposed to constant vibration, road debris, and moisture, it is a good practice to visually inspect them during routine maintenance or DOT inspections. Signs that replacement is needed include visible rust or thinning metal, cracked welds, stretched or loose straps, or any noticeable tank movement while driving. Catching wear early helps prevent more serious issues like fuel line stress or tank damage.
