Frequently Asked Questions About Peterbilt 330/335/337 Fuel Tank Covers & Bras

Will these fuel tank covers fit my specific Peterbilt 330, 335, or 337 model year?

Our fuel tank covers are designed to fit Peterbilt 330, 335, and 337 models from 2005 to current production years. However, tank configurations can vary based on wheelbase and factory options. We recommend measuring your fuel tank diameter (typically 23" or 25") and length before ordering. If you're unsure about fitment, contact us with your VIN and we'll help verify compatibility.

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

Stainless steel covers offer superior corrosion resistance and maintain their mirror finish longer, but are heavier and more expensive. Aluminum covers are lighter weight and more affordable, but require more frequent polishing to maintain shine. Both materials provide excellent protection from road debris and UV damage. Stainless is ideal for drivers prioritizing long-term appearance, while aluminum works well for those seeking good protection at a lower price point.

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

Installation typically takes 30-60 minutes per tank and requires basic hand tools. You'll need a socket set, drill with metal bits (for some models), and possibly a rivet gun for certain mounting styles. Most covers use existing tank strap holes or clamp-on designs that don't require drilling. Full covers may require removing the tank straps temporarily. We include detailed instructions with each cover, and many customers complete installation themselves without professional help.

Do fuel tank covers cause overheating or moisture buildup issues?

Quality fuel tank covers are designed with proper ventilation to prevent these issues. Look for covers with breathing holes or raised mounting that allows airflow between the cover and tank. Avoid covers that seal tightly against the tank surface. Regular inspection during routine maintenance helps catch any moisture accumulation early. In our experience, properly designed covers actually protect tanks from UV damage and temperature extremes.

What finish options are available, and how do I maintain them?

Common finishes include mirror polish, brushed, and powder-coated options. Mirror polish provides the classic chrome look but requires regular polishing with metal polish to maintain. Brushed finishes hide minor scratches better and need less maintenance. Powder-coated covers offer color options and excellent durability but can't be polished if scratched. For maintenance, wash regularly with mild soap, avoid harsh chemicals, and polish stainless or aluminum finishes every 2-3 months depending on driving conditions.
