Mack CV/GU Truck Fuel Tank Acc.

Frequently Asked Questions About Mack CV/GU Truck Fuel Tank Acc.

What types of fuel tank accessories are included in this category?

This category covers components used with the fuel tanks on Mack CV and GU series trucks, including items like fuel tank straps, mounting brackets, tank caps, sending unit assemblies, gauges, drain plugs, and related hardware. These parts are designed to support, secure, and maintain the fuel tank system on these specific Mack models.

Will these accessories fit my specific Mack CV or GU truck?

Fitment can vary depending on the model year, tank size, and configuration of your truck. Because Mack CV and GU trucks were produced over several years with different tank options, we recommend checking the listed specifications on each product page and comparing them to your truck's tank dimensions and part numbers before ordering. If you are unsure, having your VIN or original tank part number on hand will help confirm compatibility.

Are these parts made from the same material as the original equipment?

Many of our fuel tank accessories, such as straps and brackets, are made from aluminized or coated steel to help resist corrosion and withstand road exposure, similar to factory components. Material specifics are listed on individual product pages, so you can compare finish and construction details before purchasing.

How difficult is it to install a replacement fuel tank strap or bracket?

Installation difficulty depends on the specific part. Fuel tank straps and brackets typically require basic hand tools and may involve supporting the tank while the old strap or bracket is removed and the new one is installed. We recommend having a second person assist with the tank's weight during this process and following any torque specifications provided by Mack for securing the tank properly.

How do I know if my fuel tank cap, gauge, or sending unit needs to be replaced?

Common signs include fuel odor around the cap, visible cracking or a loose seal on the cap, inaccurate or erratic fuel gauge readings, or a sending unit that no longer registers fuel level correctly. If you notice any of these issues, inspecting the component and comparing it to a new replacement can help confirm whether it needs to be replaced.
