Volvo VNL Gen II Diesel Fuel Tanks

Frequently Asked Questions About Volvo VNL Gen II Diesel Fuel Tanks

Will this fuel tank fit my Volvo VNL Gen II model year?

Volvo made changes to fuel tank mounting configurations and capacities across VNL Gen II production years, so it's important to verify your truck's specific model year, tank capacity, and mounting hole pattern before ordering. Check your existing tank's dimensions and strap spacing, or provide your VIN to our sales team so we can confirm the correct fit for your truck.

What materials are these fuel tanks made from, and how do they hold up over time?

Diesel fuel tanks for the Volvo VNL Gen II are typically constructed from aluminum or steel. Aluminum tanks resist rust and are lighter, which can help with payload, while steel tanks tend to be more resistant to dents and impact damage but require proper coating to prevent corrosion. We note the material and finish for each listing so you can choose based on your priorities for weight, durability, and maintenance.

What fuel capacity options are available, and how do I know which size I need?

Replacement tanks are available in a range of capacities to match common Gen II configurations. Measure your current tank's length, diameter, and mounting strap locations, and compare that to your desired capacity, since a different size may require different straps or brackets. If you're unsure, send us your current tank's measurements and we'll help match you to a compatible option.

What's involved in installing a replacement fuel tank, and can I do it myself?

Installation generally involves draining and disconnecting the old tank, removing the mounting straps, transferring or replacing sending units and fuel lines, then mounting the new tank and reconnecting everything. Many owner-operators and shops handle this job with basic tools and a lift or jack stands, but because it involves fuel lines and proper strap torque, it should only be done by someone comfortable working with fuel systems. Always follow torque specs for mounting straps to prevent leaks or shifting during transport.

Do these fuel tanks meet DOT requirements for on-road use?

Fuel tanks sold for the Volvo VNL Gen II are designed to meet standard DOT and FMVSS requirements for commercial trucks when properly installed with the correct mounting hardware, straps, and venting. That said, compliance also depends on correct installation and use of compatible components, so double-check strap ratings and venting setup against your fleet's maintenance standards or a qualified technician's guidance.
