Frequently Asked Questions About Peterbilt 379 Fuel Tank Brackets & Straps

Will these fuel tank brackets fit my specific year Peterbilt 379?

Most aftermarket fuel tank brackets and straps for the Peterbilt 379 are designed to fit models from 1987 to 2007. However, there can be variations depending on your tank size (50-150 gallon) and whether you have a short hood or extended hood model. We recommend checking your existing bracket measurements and tank diameter before ordering. If you're unsure, contact us with your VIN and we can help verify compatibility.

What's the difference between aluminum and steel fuel tank straps?

Steel straps are the most common OEM option and typically cost less. They're durable but prone to rust over time, especially in areas with road salt. Aluminum straps resist corrosion better and weigh about 40% less, which can help with fuel economy. However, aluminum straps cost roughly 30-50% more than steel. For trucks operating in harsh weather conditions or coastal areas, the aluminum upgrade is usually worth the investment.

Can I install fuel tank brackets myself, or do I need a shop?

Installation is possible for experienced DIYers with proper equipment. You'll need a floor jack or transmission jack to support the tank, basic hand tools, and ideally a helper. The process typically takes 2-4 hours per tank. Key challenges include safely supporting the weight of a full tank (up to 1,200 lbs) and properly aligning the brackets. Many drivers choose professional installation to avoid potential fuel spills or damage, which typically costs $150-300 per tank at most truck shops.

How do I know when my fuel tank straps need replacement?

Inspect your straps every 6 months for these warning signs: visible rust or corrosion, stretched or elongated strap holes, cracks in the metal, loose bolts that won't stay tight, or any fuel tank movement/shifting. A sagging fuel tank is a critical safety issue that requires immediate attention. Most straps last 5-10 years depending on operating conditions, but trucks in northern climates may need replacement every 3-5 years due to salt exposure.

Are polished stainless steel brackets worth the extra cost?

Polished stainless steel brackets cost 2-3 times more than painted steel but offer superior corrosion resistance and maintain their appearance without regular polishing. They're popular for show trucks and owner-operators who want a maintenance-free shine. Standard painted or powder-coated steel brackets work fine for most applications and cost significantly less. Consider stainless if you plan to keep your truck long-term or want to enhance resale value.
