Frequently Asked Questions About Peterbilt 567/579 Fuel Tank Fairings

Will these fuel tank fairings fit my specific Peterbilt 567 or 579 model year?

Our fuel tank fairings are designed to fit Peterbilt 567 and 579 models from 2013 to present. However, fitment can vary based on your specific tank configuration and wheelbase. We recommend checking your truck's exact specifications, including tank size (100-150 gallon), tank mounting style (frame-mounted vs. back-of-cab), and whether you have single or dual tanks. If you're unsure, our customer service team can help verify compatibility with your VIN number.

What materials are these fairings made from, and how durable are they?

Most of our Peterbilt 567/579 fuel tank fairings are manufactured from either high-grade ABS plastic or fiberglass-reinforced polymer. Both materials offer excellent impact resistance and UV protection. ABS options are typically lighter (15-20 lbs per set) and more affordable, while fiberglass versions provide superior strength and longevity but weigh slightly more (25-30 lbs per set). All fairings feature a gel-coat finish that resists fading and cracking for 5+ years under normal conditions.

How difficult is the installation process, and what tools will I need?

Installation typically takes 2-4 hours and requires basic hand tools including a drill with metal bits, socket set, and measuring tape. Most fairings use existing mounting points on your truck's frame, though some applications may require drilling 4-6 new holes. The most challenging aspect is often ensuring proper alignment and clearance around fuel lines and DEF tanks. We include detailed instructions with diagrams, and many customers successfully complete installation without professional help.

What finish options are available, and can they be painted?

Our fuel tank fairings come in three standard finishes: primer black (ready for custom painting), polished stainless steel look, and chrome-plated ABS. The primer black option is specifically designed for painting and requires minimal prep work - just clean, prime if needed, and apply your choice of automotive paint. Chrome and stainless finishes should not be painted as they're designed to maintain their appearance without additional coating.

Do these fairings affect fuel tank access or maintenance?

Quality fuel tank fairings are designed with maintenance in mind. Most models feature removable access panels or quick-release mounting systems that allow you to reach fuel caps, drain valves, and tank straps without complete removal. Some fairings may add 5-10 minutes to routine fuel filter changes or tank inspections. We recommend choosing fairings with hinged or bolt-on access doors if you perform frequent maintenance or operate in harsh conditions requiring regular tank cleaning.
