Sterling Acterra Truck Fuel Tanks

Frequently Asked Questions About Sterling Acterra Truck Fuel Tanks

What fuel tank sizes are available for Sterling Acterra trucks, and how do I know which one fits my model?

Sterling Acterra fuel tanks typically come in 25, 35, 50, and 60-gallon capacities. To determine the correct size for your truck, check your door jamb sticker for the original tank specification or measure your existing tank's dimensions. Acterra models from 2003-2009 commonly use either single rectangular tanks mounted on the frame rail or dual tank configurations. The tank size often depends on your truck's wheelbase and cab configuration. Always verify the mounting strap spacing and inlet/outlet positions match your current setup before ordering.

Are aftermarket fuel tanks for Sterling Acterra trucks made of steel or aluminum, and which is better?

Most replacement fuel tanks for Sterling Acterra trucks are available in both aluminized steel and aluminum options. Aluminized steel tanks cost less and offer good corrosion resistance for 5-7 years in normal conditions. Aluminum tanks cost approximately 40-60% more but provide superior corrosion resistance, especially in areas using road salt, and typically last 10-15 years. Aluminum tanks are also 30-40% lighter, which can improve fuel economy. Consider your climate, budget, and how long you plan to keep the truck when choosing between materials.

What are the most common installation challenges when replacing a Sterling Acterra fuel tank?

The primary installation challenges include properly draining the old tank (plan for 2-3 hours if full), dealing with rusted mounting straps and bolts that may need cutting, and ensuring proper fuel line connections. Many installers report difficulty accessing the fuel pump and sending unit connections on top of the tank. You'll need a transmission jack or fuel tank jack for safe removal and installation. Budget 4-6 hours for a DIY installation. Common mistakes include not transferring the fuel pump and sending unit properly or forgetting to check the condition of fuel lines and replace them if cracked or deteriorated.

Do I need to replace other components when installing a new fuel tank on my Sterling Acterra?

Yes, several components should be inspected and potentially replaced during fuel tank installation. Always install new mounting straps (even if old ones look okay) as they fatigue over time. Replace the fuel filler neck grommet and vent hose to prevent vapor leaks. Inspect fuel lines for cracks or deterioration - rubber lines older than 5 years should be replaced. The fuel pump and sending unit can typically be transferred if working properly, but consider replacing the pump if your truck has over 150,000 miles. New fuel tank mounting bushings are recommended to reduce vibration and tank movement.

What's the difference between OEM and aftermarket fuel tanks for Sterling Acterra trucks?

OEM Sterling fuel tanks are no longer manufactured since Daimler discontinued the Sterling brand in 2009. Quality aftermarket tanks from reputable manufacturers meet or exceed OEM specifications and often feature improvements like better baffling to reduce fuel slosh and thicker material gauges. Aftermarket tanks typically cost 40-60% less than what OEM tanks sold for. Key things to verify on aftermarket tanks include proper SAE J1321 certification, correct inlet/outlet port sizing and positioning, and appropriate pressure relief venting. Most aftermarket tanks carry 1-2 year warranties compared to the original 1-year OEM warranty.
