Freightliner FLD SBA Fuel Tanks

Frequently Asked Questions About Freightliner FLD SBA Fuel Tanks

What year models and specific Freightliner FLD variants are these SBA fuel tanks compatible with?

These SBA (Set Back Axle) fuel tanks are designed specifically for Freightliner FLD models from 1989 to 2002, including the FLD112, FLD120, and FLD132 Classic variants. The SBA configuration means these tanks are engineered for trucks with the axle positioned further back from the standard location. Before ordering, verify your truck's OEM and confirm it has the set back axle configuration, as these tanks will not properly fit standard axle FLD models.

What materials are these fuel tanks made from, and how do they compare to OEM tanks in terms of durability?

Our Freightliner FLD SBA fuel tanks are available in both aluminum and steel options. Aluminum tanks typically weigh 40-50% less than steel equivalents and resist corrosion better, making them ideal for weight-conscious operations or coastal environments. Steel tanks offer superior impact resistance and are often more budget-friendly. Both materials meet or exceed OEM specifications, with aluminum tanks featuring 0.125-inch wall thickness and steel tanks using 14-gauge construction for long-term reliability.

What installation challenges should I expect, and can I install these myself or do I need a professional?

Installation typically takes 2-4 hours per tank for experienced mechanics. Common challenges include aligning the mounting straps properly with existing frame holes and ensuring fuel line connections are secure. You'll need basic hand tools, a floor jack or transmission jack for support, and potentially new mounting hardware if your existing straps show wear. While DIY installation is possible for those with mechanical experience, professional installation is recommended if you're unfamiliar with fuel system work, as improper installation can lead to leaks or tank damage.

What capacity options are available, and how do I determine the right size for my truck?

SBA fuel tanks for Freightliner FLD models typically range from 50 to 150 gallons, with 100 and 120-gallon options being most popular. To determine the right size, measure your existing tank dimensions and available frame space between the cab and drive axles. Consider your typical route distances and payload requirements - larger tanks add weight but reduce fuel stops. Most SBA configurations can accommodate dual 100-gallon setups or single 120-150 gallon tanks, depending on your frame rail spacing.

Do these tanks come with mounting hardware, and what additional parts might I need for a complete installation?

Most SBA fuel tanks ship as tank-only units without mounting hardware. You'll typically need to purchase mounting straps, brackets, and rubber isolators separately, or reuse existing hardware if it's in good condition. Additional items often required include new fuel pickup tubes, sending units, fuel caps, and potentially crossover lines for dual tank setups. We recommend inspecting your current fuel lines, fittings, and shut-off valves during installation, as these components often need replacement after years of service.
