Kenworth T300-T450 Fuel Tanks

Frequently Asked Questions About Kenworth T300-T450 Fuel Tanks

What sizes and capacities are available for Kenworth T300-T450 fuel tanks?

We offer fuel tanks ranging from 50 to 150 gallons for the T300-T450 series. The most common sizes are 60, 80, 100, and 120-gallon tanks. Round tanks typically come in 23" or 25" diameters, while D-shaped tanks are available for specific chassis configurations. Always verify your frame rail spacing and available mounting area before ordering, as the T300 and T450 have different frame widths that affect tank fitment.

Will these fuel tanks fit my specific year and model Kenworth?

Our fuel tanks are designed to fit Kenworth T300 models from 1994-2007 and T450 models from 2008-2019. However, compatibility can vary based on your truck's wheelbase, cab configuration, and existing fuel system setup. Trucks with aftermarket exhaust systems or auxiliary equipment may require different strap lengths or mounting brackets. We recommend checking your current tank's part number or contacting us with your OEM for exact fitment verification.

What material options are available and which is best for my application?

We stock both aluminum and steel fuel tanks. Aluminum tanks are lighter (reducing overall vehicle weight by 50-70 pounds compared to steel), resist corrosion better, and are ideal for trucks operating in northern climates with road salt exposure. Steel tanks cost approximately 30% less than aluminum, offer superior impact resistance, and work well for heavy-duty vocational applications. Both materials meet DOT specifications and include the same warranty coverage.

Can I install these fuel tanks myself or do I need professional installation?

While experienced mechanics can install these tanks, we recommend professional installation due to fuel system safety requirements. Installation typically takes 2-4 hours and requires draining the existing tank, transferring the fuel sending unit, connecting fuel lines with proper DOT-approved fittings, and ensuring proper grounding. You'll need basic hand tools, a floor jack, and potentially new fuel line fittings. Always check local regulations, as some states require certified technicians for fuel system work.

Do these tanks come with mounting hardware and what additional parts might I need?

Our fuel tanks include the tank shell, drain plug, and mounting tabs welded in place. Mounting straps, brackets, sending units, and fuel caps are sold separately to accommodate different configurations. Most installations require new fuel line fittings, vent lines, and potentially a sending unit gasket. For complete replacement, budget for an additional $150-300 in mounting hardware and accessories beyond the tank price.
