Frequently Asked Questions About Kenworth T800 Diesel Fuel Tanks
What size fuel tanks are available for my Kenworth T800, and how do I determine the right capacity?
Kenworth T800 fuel tanks typically range from 50 to 150 gallons per tank, with 100-120 gallon tanks being the most common. To determine the right capacity, consider your typical route distance, payload weight, and mounting space. Measure your existing tank dimensions or check your truck's spec sheet for the original tank size. Most T800 models can accommodate dual tank setups, allowing for 200-300 gallons total capacity. Remember that larger tanks add weight and may affect your payload capacity.
Will these fuel tanks fit my specific year and model T800?
Fuel tank compatibility for Kenworth T800s generally falls into three categories: 1987-2007 models with 26-inch steps, 2008-2014 models with updated mounting brackets, and custom configurations. Most aftermarket tanks are designed to fit standard T800 frame rails with 34-inch spacing. However, trucks with extended cabs, specialized suspensions, or custom wheelbases may require different brackets or modifications. Always verify your frame rail width, step box configuration, and year model before ordering to ensure proper fitment.
What material options are available, and which is best for durability?
Diesel fuel tanks for the T800 come in two primary materials: aluminum and steel. Aluminum tanks are lighter (reducing overall vehicle weight by 50-100 pounds per tank), resist corrosion better, and are ideal for trucks operating in harsh weather conditions. Steel tanks cost less upfront but require regular maintenance to prevent rust. Most professional drivers prefer aluminum for long-term reliability, especially if running in northern states where road salt is common. Both materials meet DOT standards when properly manufactured.
What installation challenges should I expect when replacing my T800 fuel tanks?
Installing replacement fuel tanks typically requires 3-4 hours per tank for experienced mechanics. Common challenges include: aligning new mounting straps with existing frame holes (some drilling may be required), transferring fuel sending units and draw tubes from old tanks, and ensuring proper clearance from exhaust components. You'll need basic hand tools plus tank straps, mounting hardware, and new fuel lines. Many installers recommend replacing rubber fuel hoses and checking crossover valve functionality during tank replacement. Professional installation runs $200-400 per tank depending on complexity.
Can I upgrade from a single to dual tank setup on my T800?
Yes, most T800 models can be upgraded from single to dual tank configurations. This upgrade requires a compatible tank for the passenger side, additional mounting straps and brackets, a crossover fuel line kit, and potentially a new fuel gauge sending unit. The main considerations are frame rail clearance, exhaust routing, and whether your fuel system supports dual tank operation. Budget approximately $800-1500 for a complete dual tank upgrade including parts and installation. This modification typically adds 300-400 miles to your range between fuel stops.
