Frequently Asked Questions About Kenworth T660 Diesel Fuel Tanks

Will this fuel tank fit my Kenworth T660 without modification?

Fuel tanks vary by capacity, mounting bracket configuration, and strap style, so it's important to match the tank to your truck's specific frame width, wheelbase, and mounting hole pattern. Check the listed specifications against your original tank or your Kenworth build sheet before ordering to ensure a proper fit.

What materials are available, and which one should I choose?

Diesel fuel tanks for the T660 are typically offered in aluminum or steel. Aluminum tanks are lighter and resist corrosion well, making them a popular choice for fuel economy and longevity, while steel tanks tend to be more durable against impact and abrasion but add extra weight. Your choice often comes down to priorities around weight savings versus rugged durability.

What capacity options are offered, and how do I know which size I need?

Capacities commonly range from smaller auxiliary sizes up to larger tanks designed for long-haul use. Consider your typical routes, fuel stop availability, and any weight or clearance restrictions from your fleet or state regulations when selecting a tank size, and compare it to the capacity of your current tank to maintain similar range.

Can I install a replacement fuel tank myself, or should I have a professional do it?

While experienced DIYers with the right lifting equipment and hand tools can replace a fuel tank, the process involves working with fuel lines, straps, sending units, and sometimes crossmembers, so many owners choose to have the installation done by a qualified truck technician. This helps ensure proper sealing, secure mounting, and correct reconnection of fuel and vent lines.

Do these tanks come with mounting straps, sending units, or other hardware included?

Included components vary by listing, so always check the product description to see whether mounting straps, sending units, fuel gauges, or brackets are included or sold separately. If a component isn't included, you may be able to reuse your existing hardware if it's still in good condition and compatible with the new tank.
