Frequently Asked Questions About GMC Brigadier Truck Fuel Tank Accessories

Will these fuel tank accessories fit my specific GMC Brigadier model year?

Most fuel tank accessories for GMC Brigadier trucks are designed to fit models from 1978-1988. However, there can be variations between early and late production years. We recommend checking your VIN and confirming your tank dimensions before ordering. Common tank sizes include 50, 75, and 100-gallon capacities. If you're unsure, contact our support team with your truck's year and VIN for verification.

What material are the fuel tank straps and brackets made from, and how long do they typically last?

Our fuel tank straps and brackets are manufactured from either galvanized steel or stainless steel, depending on the specific product. Galvanized options typically last 5-8 years in normal conditions, while stainless steel versions can last 15+ years. For trucks operating in high-salt environments or harsh weather conditions, we strongly recommend stainless steel accessories for maximum durability and corrosion resistance.

Do I need special tools or professional installation for fuel tank accessories?

Basic fuel tank strap and bracket installations can typically be completed with standard hand tools including wrenches, sockets, and a jack to support the tank. However, you'll need to safely drain and support the fuel tank during installation. Many customers complete this job in 2-3 hours. For sending units or fuel tank replacements, we recommend professional installation due to safety concerns with fuel handling and proper sealing requirements.

Are aftermarket fuel caps compatible with my Brigadier's tank, and do they maintain proper venting?

Yes, our aftermarket fuel caps are designed to match OEM specifications for GMC Brigadier trucks. They include proper venting mechanisms to prevent vacuum buildup and maintain EPA compliance. We offer both locking and non-locking versions. Make sure to select the correct thread size - most Brigadiers use either 2" or 2.5" diameter caps. Check your existing cap or tank opening before ordering.

What's the difference between aluminum and steel fuel tanks for my Brigadier?

Aluminum tanks are 40-50% lighter than steel versions and won't rust, making them ideal for trucks in corrosive environments. However, they cost 20-30% more than steel tanks. Steel tanks are more impact-resistant and less expensive but require proper coating maintenance to prevent rust. Both types fit the same mounting points. Consider aluminum if weight savings or corrosion resistance is priority, steel if you need maximum durability at a lower cost.
