Frequently Asked Questions About Kenworth T660 Fuel Tank Covers & Bras

What are the differences between stainless steel and chrome plastic fuel tank covers for my T660?

Stainless steel covers offer superior durability and resistance to rust, road salt, and harsh weather conditions, typically lasting 10+ years with proper care. They're heavier (around 15-20 lbs per cover) and cost more upfront but maintain their appearance longer. Chrome plastic covers are lighter (5-8 lbs), easier to install, and cost less initially, but may show wear, fading, or cracking after 3-5 years of exposure to UV rays and road chemicals. Most drivers choose stainless for long-term value and plastic for budget-conscious upgrades.

Will these fuel tank covers fit my specific Kenworth T660 model year?

Most fuel tank covers are designed to fit Kenworth T660 models from 2008-2017, but fitment can vary based on your tank size and configuration. Standard 100-150 gallon round tanks typically use universal covers, while step tanks or custom configurations may require specific models. Always verify your tank diameter (usually 23" or 26") and mounting bracket style before ordering. If your T660 has aftermarket tanks or modified fuel systems, contact us with your VIN and tank measurements for proper fitment guidance.

Can I install fuel tank covers myself, or do I need professional help?

Installation is straightforward and takes about 30-60 minutes per tank with basic tools. You'll need a socket wrench set, screwdriver, and possibly drilling equipment for some models. Most covers use existing mounting points or straps that wrap around the tank. The main challenges are accessing tight spaces and properly aligning heavy stainless covers. Having a helper makes the job easier, especially for lifting and positioning. Professional installation typically costs $50-100 per tank if you prefer expert installation.

How do fuel tank covers affect fuel temperature and DEF system performance?

Quality fuel tank covers actually help regulate fuel temperature by providing an extra layer of insulation against extreme heat and cold. This can improve fuel efficiency slightly and reduce condensation issues. For trucks with DEF tanks, ensure your covers don't obstruct DEF tank vents or sensors. Most modern designs account for this, but double-check clearances during installation. In extreme cold climates, covers can help prevent diesel gelling by maintaining more consistent tank temperatures.

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

Stainless steel covers need monthly washing with mild soap and water, followed by a stainless steel polish every 3-4 months to prevent water spots and maintain shine. Avoid harsh chemicals or abrasive cleaners that can scratch the finish. Chrome plastic covers require gentler care with non-abrasive cleaners and should be waxed quarterly to protect against UV damage. Both types benefit from regular inspection of mounting hardware for looseness or corrosion, especially after winter driving or exposure to road salt.
