Sterling Acterra Truck Fuel Tanks

Frequently Asked Questions About Sterling Acterra Truck Fuel Tanks

What sizes and shapes of fuel tanks are available for the Sterling Acterra?

Sterling Acterra fuel tanks are available in a range of capacities and shapes, including round and D-shaped (rectangular) styles, to match the configuration of your truck. Common sizes range from smaller capacities used on straight trucks to larger tanks found on Class 7 and 8 models. Always check your current tank's dimensions and mounting bracket spacing before ordering a replacement to ensure a proper fit.

Are these fuel tanks made from aluminum or steel, and does it matter?

Fuel tanks for the Sterling Acterra are typically offered in aluminum. Aluminum tanks are lighter in weight, which can help with overall vehicle payload, and they resist rust better than steel over time. When comparing options, look at the gauge and welding quality, as thicker material and solid weld seams generally hold up better to road vibration and daily wear.

Will a replacement tank bolt up to my existing mounting brackets and straps?

In most cases, a tank designed for the Acterra will use the factory mounting strap and bracket layout, but it's important to verify strap spacing, tank diameter, and end cap style before purchasing. If you are switching between a round and D-shaped tank, or changing capacity, you may need to source new straps or brackets to get a secure fit.

What should I check for when it comes to fittings and sending unit placement?

Fuel tanks can vary in where the fill neck, vent, pickup tube, and sending unit ports are located. Before ordering, compare the port locations and thread sizes on the replacement tank to your existing tank or your truck's fuel line and sending unit setup. This helps avoid extra modification work or the need for adapter fittings during installation.

How do I know if I need a new tank versus having my current one repaired?

If your tank has minor surface corrosion or a small ding, repair may be an option. However, cracks near weld seams, significant corrosion, or damage around the mounting straps and fittings are usually signs that replacement is the safer and more reliable choice. A tank that has been repeatedly patched or shows fuel seepage should be replaced rather than repaired again.
