Frequently Asked Questions About GMC Brigadier Truck Fuel Tank Brackets & Straps

What years and models of GMC Brigadier trucks do these fuel tank brackets and straps fit?

Our fuel tank brackets and straps are designed to fit GMC Brigadier trucks from 1988 to 1998. However, compatibility can vary based on your specific fuel tank configuration and size. We recommend checking your existing bracket measurements and tank capacity (typically 50, 75, or 100-gallon tanks) before ordering. If you're unsure about fitment, contact our support team with your VIN number for exact compatibility verification.

Are these brackets made from galvanized steel or will they rust quickly?

Most of our GMC Brigadier fuel tank brackets feature either galvanized steel construction or a powder-coated finish for corrosion resistance. The straps typically come with a zinc-plated coating. For maximum longevity in harsh conditions or road salt exposure, we recommend applying an additional rust preventative coating during installation. Expected lifespan under normal conditions is 8-12 years, though this varies based on your operating environment.

Do I need special tools or professional installation for replacing fuel tank brackets and straps?

While professional installation is always an option, many truck owners successfully complete this job with basic tools. You'll need jack stands or a transmission jack to support the fuel tank, standard wrenches (typically 9/16" and 5/8"), and potentially a reciprocating saw if removing corroded brackets. The process usually takes 2-3 hours. Always drain the fuel tank before starting and follow proper safety procedures when working with fuel systems.

What's the difference between OEM-style and universal fuel tank brackets?

OEM-style brackets are designed to match the original GMC Brigadier specifications with exact mounting points and dimensions. Universal brackets may require minor modifications or additional hardware but often cost less. OEM-style brackets typically offer easier installation and better long-term fit, while universal options provide flexibility if you've modified your fuel system or need to accommodate non-standard tank sizes.

How do I know when it's time to replace my fuel tank brackets and straps?

Inspect your brackets and straps during regular maintenance for signs of excessive rust, cracks, bent metal, or stretched straps. Warning signs include fuel tank movement or noise while driving, visible sagging of the tank, fuel odors from stress on connections, or failed DOT inspections. As a preventive measure, many operators replace straps every 5-7 years and brackets every 10-12 years, especially in corrosive environments.
