Frequently Asked Questions About Kenworth T700 Fuel Tank Covers & Bras

What's the difference between stainless steel and chrome plastic fuel tank covers for my T700?

Stainless steel covers are heavier duty, typically 16-20 gauge, and offer superior corrosion resistance and longevity - expect 10+ years of service with proper care. Chrome plastic covers are lighter weight, easier to install, and cost about 40-60% less, but may show wear after 3-5 years depending on weather exposure. Stainless steel requires occasional polishing to maintain shine, while chrome plastic maintains its finish longer but can crack or fade over time.

Will these fuel tank covers fit my specific Kenworth T700 model year?

Most fuel tank covers are designed to fit Kenworth T700 models from 2008-2019. However, tank sizes vary (100-150 gallon capacities), and some T700s have dual tanks while others have single configurations. Before ordering, measure your tank diameter (typically 23" or 26") and confirm whether you have round or D-shaped tanks. Extended hood models may require different mounting brackets than standard hood versions.

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

Installation typically takes 30-45 minutes per tank and requires basic hand tools: socket set, screwdrivers, and possibly a drill for custom mounting. Most covers use existing mounting points or heavy-duty straps that wrap around the tank. The main challenge is accessing tight spaces between the tank and frame rails. Some drivers report needing to slightly loosen tank straps for easier fitment. Professional installation runs $50-100 per tank if you prefer not to DIY.

Do fuel tank covers affect fuel efficiency or cause any operational issues?

Quality fuel tank covers have minimal impact on fuel efficiency - typically less than 0.5% change in MPG. However, poorly fitted covers can create wind drag or vibration noise at highway speeds. Ensure covers have proper ventilation slots to prevent moisture buildup between the cover and tank, which can accelerate corrosion. Some drivers report improved aerodynamics with full-wrap designs versus half covers.

What maintenance is required to keep fuel tank covers looking good?

Stainless steel covers need polishing every 2-3 months with metal polish to prevent water spots and maintain mirror finish. Chrome plastic requires only soap and water cleaning but should be waxed quarterly to prevent UV damage. Check mounting hardware monthly for looseness - road vibration can work bolts loose over time. In winter climates, remove salt buildup promptly to prevent corrosion of mounting brackets and hardware.
