Frequently Asked Questions About Kenworth W900A Diesel Fuel Tanks

Will a replacement fuel tank fit my Kenworth W900A without modification?

Fuel tanks are typically offered in various diameters, lengths, and mounting configurations to match specific W900A model years and frame setups. Always check the listed dimensions, mounting bracket spacing, and gallon capacity against your truck's original tank before ordering to ensure a proper fit.

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

Diesel fuel tanks for the W900A are commonly available in aluminum or steel. Aluminum tanks tend to resist corrosion better and are lighter in weight, while steel tanks are often valued for their durability and strength. The right choice depends on your priorities for weight savings versus long-term ruggedness in your specific operating environment.

What finish options are available, and do I need to treat the tank after installation?

Tanks may come in a raw, polished, or painted finish depending on the manufacturer and material. Aluminum tanks are often left unpainted since the material naturally resists rust, while steel tanks may require a protective coating or paint to prevent corrosion. Check the product listing for finish details so you know what to expect out of the box.

What's involved in installing a new diesel fuel tank on my W900A?

Installation generally involves removing the old tank, transferring or replacing mounting straps and brackets, connecting fuel lines and sending unit wiring, and securing the new tank to the frame rail. Because fuel system work involves safety considerations, we recommend having the installation performed by a qualified technician familiar with heavy-duty truck fuel systems.

Are these fuel tanks compliant with DOT and safety regulations?

Reputable fuel tank manufacturers design their tanks to meet applicable DOT and FMVSS standards for heavy-duty trucks. That said, specific compliance details can vary by brand and model, so review the manufacturer specifications provided in the listing or contact our team if you need documentation for a particular tank.
