Frequently Asked Questions About Peterbilt 359 Fuel Tank Accessories

Will these fuel tank straps and brackets fit my specific year Peterbilt 359?

Most fuel tank accessories are designed to fit Peterbilt 359 models from 1967-1987, but fitment can vary based on your specific tank configuration. Standard 100-150 gallon round aluminum tanks typically use universal mounting hardware. However, if you have aftermarket tanks or custom setups, measure your tank diameter (typically 23" or 26") and verify the strap length before ordering. For modified frames or extended hood models, you may need longer straps or custom brackets.

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

Aluminum straps are lighter weight and more affordable, making them ideal for drivers focused on weight savings. They resist corrosion well but can show wear from road salt over time. Stainless steel straps cost more upfront but offer superior durability and maintain their appearance longer, especially in harsh weather conditions. Stainless straps also handle higher tension better, making them preferable for heavy-duty applications or trucks that see rough terrain regularly.

Can I install fuel tank steps and accessories myself, or do I need a shop?

Most fuel tank steps and basic accessories can be installed with standard tools in 2-3 hours. You'll need a socket set, drill with metal bits, and potentially a rivet gun. The main challenges are properly aligning the steps to avoid interference with existing components and ensuring secure mounting to prevent vibration. If you're adding electrical components like LED lights to your tank steps, basic wiring knowledge is helpful. Always support the fuel tank properly during installation to prevent damage or injury.

How do I choose between polished, chrome, and painted fuel tank accessories?

Polished aluminum offers a classic look and is easy to maintain with regular polishing but requires more upkeep to prevent oxidation. Chrome provides the brightest shine and resists tarnishing but can peel if damaged and is typically the most expensive option. Painted finishes in black or custom colors are most practical for work trucks, hiding minor damage and requiring minimal maintenance. Consider your truck's use - show trucks benefit from chrome, while working trucks often prefer painted or polished aluminum.

What size fuel tank hangers do I need, and are they sold in pairs?

Fuel tank hangers are typically sized by tank diameter and mounting width. Standard Peterbilt 359 setups use 23" or 26" diameter hangers with 34" to 36" frame rail spacing. Most quality hangers are sold individually, so you'll need to order two for a complete installation. Heavy-duty hangers rated for 150+ gallon tanks are recommended even for smaller tanks, as the extra strength prevents sagging over time. Always replace both hangers as a set to ensure even support and prevent premature wear.
