GMC General Truck Fuel Tanks

Frequently Asked Questions About GMC General Truck Fuel Tanks

Will this fuel tank fit my GMC General truck without modifications?

Fuel tanks are designed to match the mounting configuration, capacity, and shape used on GMC General trucks, but fitment can vary depending on the model year and how your specific truck was originally equipped. Be sure to check the tank's dimensions, mounting hole pattern, and capacity against your truck's original tank before ordering, and reach out to our team if you are unsure about compatibility.

What material are these fuel tanks made from, and how does that affect durability?

GMC General fuel tanks are commonly available in aluminum or steel. Aluminum tanks tend to resist corrosion well and are lighter in weight, which can help with fuel efficiency, while steel tanks are often valued for their strength and impact resistance. The right choice usually comes down to your priorities for weight savings versus rugged durability, as well as the climate and conditions your truck operates in.

How do I properly install a replacement fuel tank?

Installation typically involves draining and disconnecting the old tank, removing the mounting straps or brackets, and transferring or replacing components such as the sending unit, fuel lines, and vent fittings. Because fuel systems involve pressurized lines and flammable materials, we recommend having the installation performed by a qualified technician or someone experienced with fuel tank replacement to ensure everything is sealed and secured correctly.

Do these tanks come with the mounting straps, sending unit, and other hardware included?

This varies by product listing, so it's important to check the specific product description before purchasing. Some fuel tanks are sold as a standalone tank only, while others may include straps or mounting hardware. If your existing sending unit or fuel cap is in good condition, you may be able to reuse it on the new tank, but always confirm thread size and fitment first.

What finish options are available, and how do I maintain the tank's appearance and integrity over time?

Fuel tanks are generally available in raw or polished aluminum, or coated steel finishes. Polished aluminum offers a bright, finished look but may require periodic cleaning and polishing to maintain its shine, especially when exposed to road salt and grime. Steel tanks with a protective coating should be inspected periodically for chips or scratches that could lead to rust, and any damage to the coating should be addressed promptly to prevent corrosion.
