Frequently Asked Questions About Kenworth W900A Fuel Tank Accessories

Will these fuel tank straps and brackets fit my specific year W900A?

Most of our fuel tank accessories are designed to fit Kenworth W900A models from 1961-1985. However, there can be variations between early and late production years. We recommend checking the product description for specific year ranges or contacting our team with your VIN to confirm compatibility. Pay special attention if you have a 1961-1965 model, as these early years sometimes have different mounting configurations.

What's the difference between aluminum and stainless steel fuel tank straps?

Aluminum straps are lighter weight (about 40% less than steel) and resist corrosion well, making them ideal for weight-conscious applications. They typically cost less but may show wear faster in harsh conditions. Stainless steel straps offer superior strength and durability, maintain their polished appearance longer, and handle extreme weather better. Most professional drivers choose stainless for long-term reliability, while aluminum works well for show trucks or lighter duty applications.

Do I need special tools or modifications to install fuel tank mounting brackets?

Standard installation typically requires basic hand tools including socket wrenches, torque wrench, and potentially a drill for some aftermarket accessories. Most direct replacement parts bolt into existing holes without modification. However, if you're upgrading from rubber straps to metal bands or adding auxiliary tanks, you may need to drill new mounting holes. Installation usually takes 2-4 hours per tank. We always recommend having a second person assist with tank positioning during installation.

What size fuel tank steps and which mounting style should I choose?

Fuel tank steps come in various sizes, with 26-inch and 30-inch being most common for W900A models. The size depends on your tank diameter and personal preference. For mounting styles, bolt-on steps offer easy installation and removal, while weld-on options provide a cleaner look and stronger attachment. Consider your tank material - aluminum tanks require special welding procedures. Most drivers prefer bolt-on for versatility unless they're doing a full restoration.

How do I know if I need 100-gallon or 150-gallon tank straps and hardware?

Measure your tank diameter to determine the correct size. 100-gallon tanks typically measure 23-24 inches in diameter, while 150-gallon tanks measure 26-28 inches. The mounting strap length differs by about 8-10 inches between these sizes. Using incorrect straps can cause dangerous tank movement or damage. Check your door jamb sticker or original equipment specs if you're unsure of your tank capacity. When in doubt, measure the circumference of your tank and divide by 3.14 to get the diameter.
