Frequently Asked Questions About Peterbilt 375/377 Fuel Tank Covers & Bras

Will these fuel tank covers fit my specific year Peterbilt 375 or 377?

Most fuel tank covers for Peterbilt 375/377 models are designed to fit trucks manufactured from 1987 through 2007. However, fitment can vary based on your tank size and mounting configuration. Standard 26-inch diameter round tanks typically have universal fitment, but trucks with 23-inch tanks or custom setups may require different covers. We recommend measuring your tank diameter and checking for step boxes or other modifications before ordering.

What's the difference between vinyl and stainless steel fuel tank covers?

Vinyl covers are lightweight, cost-effective options that protect against road debris and UV damage while being easy to install and remove for maintenance. They typically last 3-5 years with proper care. Stainless steel covers offer superior durability and a premium appearance but require more permanent mounting and cost significantly more. Vinyl is ideal for drivers wanting protection with easy tank access, while stainless suits those prioritizing long-term aesthetics and maximum durability.

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

Vinyl fuel tank covers typically install in 30-45 minutes per tank using the included straps and buckles - no drilling required. You'll need basic hand tools to adjust the straps and possibly a heat gun to help the vinyl conform in cold weather. Stainless steel covers require 1-2 hours per tank and involve drilling mounting holes, requiring a drill, metal bits, and mounting hardware. Many drivers successfully install vinyl covers themselves, while stainless installations often benefit from professional help.

Do these covers interfere with fuel cap access or tank maintenance?

Quality vinyl fuel tank covers feature fuel door cutouts or removable flaps for easy fuel cap access without removing the entire cover. For maintenance requiring full tank inspection, vinyl covers can be removed in minutes by releasing the straps. Stainless covers typically have permanent fuel door cutouts but require unbolting for complete removal. Consider how often you need tank access when choosing between materials.

How do these covers hold up in extreme weather and road conditions?

Heavy-duty vinyl covers rated for commercial use withstand temperatures from -40?F to 160?F and resist fading, cracking, and road salt damage when properly maintained. Look for covers with UV inhibitors and reinforced edges for maximum longevity. In extreme cold, vinyl may become stiff but regains flexibility as it warms. Regular cleaning and occasional treatment with vinyl protectant extends life significantly. Avoid budget covers with thin material or weak stitching that fail quickly under commercial driving conditions.
