Kenworth T880 Fuel Tanks

Frequently Asked Questions About Kenworth T880 Fuel Tanks

What size fuel tanks are available for the Kenworth T880, and how do I determine which capacity I need?

Kenworth T880 fuel tanks typically range from 60 to 150 gallons, with 100 and 120-gallon options being the most common. To determine the right capacity, consider your typical route distance, payload weight, and fuel stop availability. Long-haul drivers often prefer dual 120-gallon setups for extended range, while regional operators may find single 100-gallon tanks sufficient. Remember that larger tanks add weight, which can impact your payload capacity.

Will aftermarket fuel tanks fit my specific T880 model year, and what mounting hardware is required?

Most aftermarket fuel tanks are designed to fit T880 models from 2013 to present, but frame rail spacing and step configurations can vary between model years and specifications. You'll need to verify your frame rail width (typically 34" or 34.5") and existing mounting bracket style. Standard installations require mounting straps, brackets, and anti-slip pads. Some 2020+ models may have different DEF tank configurations that affect fuel tank placement, so double-check clearances before ordering.

What's the difference between aluminum and steel fuel tanks, and which is better for my T880?

Aluminum tanks are lighter (saving 50-100 lbs per tank), resist corrosion better, and are standard on most T880s. They typically cost 20-30% more than steel but offer better fuel economy due to weight savings. Steel tanks are more impact-resistant and less expensive but require regular inspection for rust, especially in salt-belt states. For most applications, aluminum is preferred unless you're operating in extreme conditions where impact damage is a concern.

Can I install a fuel tank myself, or do I need professional installation?

While experienced mechanics can install fuel tanks, we recommend professional installation due to safety and regulatory requirements. Installation involves proper grounding, fuel line connections, and ensuring DOT compliance. The process typically takes 3-4 hours per tank and requires draining existing fuel, removing old tanks, transferring sending units, and properly torquing all connections. Improper installation can lead to leaks, electrical issues, or DOT violations.

Do replacement fuel tanks come with sending units, straps, and other necessary components?

Most replacement fuel tanks are sold as bare units without sending units, fuel caps, or mounting hardware. You'll typically need to transfer your existing sending unit or purchase a new one separately. Mounting straps and brackets are usually sold separately unless specified as a complete kit. Budget an additional $150-300 for mounting hardware, sending units, and miscellaneous fittings if you're doing a complete replacement rather than transferring existing components.
